The entire system consists of the cleat, the fasteners-including nuts, bolts and washers, the deck or other Aluminum Boat Deck Cleats 95 mounting platform, backing plates-and the line. You rely on that system Best Aluminum Boat Deck Paint Zip to keep your boat secure, even in conditions like storms or towing that subject the system to tremendous stress and shock loads. In this test, the BoatUS Foundation wanted to examine one of Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 the most critical links in the system: cleats.
Working in conjunction with the University of Virginia School of Engineering, we set up laboratory testing apparatus to simulate the loads placed on cleats of different design aluminum boat deck cleats 95 and materials.
Our goal was to determine the direction and magnitude of the smallest force required to deform or break a cleat fixed to a rigid Aluminum Boat Deck Cleats 95 surface with mounting hardware specified by the manufacturer. The Foundation tested 11 six inch cleats made of nylon, aluminum, marinium a magnesium-aluminum- Aluminum Boat Deck Cleats 95 titanium-beryllium alloychrome-plated zinc, bronze, stainless steel, and Zamac a high-grade die-cast lauminum alloy. Five of the cleats were two-hole; six were four-hole.
Admittedly, the steel plate is not the same as a deck mounting on a boat, but it prevents the aluminum boat deck 95 Boat Cleats Deck Aluminum cleats 95 from pulling out, and it eliminates different boat decking materials as a variable, so that only the cleat aluminum boat deck cleats 95 is being tested. To ensure uniformity, the cleats were mounted to the steel plate using manufacturer recommended sizes of Aluminum Boat Deck Cleats 95 flathead stainless steel bolts, nuts and washers, all tightened to precisely the same torque.
Plastic- coated cable was used to ensure that Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 the cause of a failure would not be the aluminum boat deck cleats 95 or a weak point caused by wire abrading the cleat. The test was conducted under strictly controlled laboratory conditions. We suspect, however, that different tests might produce slightly celats results, Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 because the failure baot in each pull are dependent on so many variables.
For example, the seating of the fasteners relative to Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 the exact center of the holes in the feet has a direct effect on load distribution and consequently the amount of stress Aluminum Boat Deck Cleats 95 placed on any given part of the cleat. Similarly, using a larger size line aljminum produce different results, because larger line exerts Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 more force on the bottom of the horn and less on the top of the leg.
It is reassuring, however, that the Aluminum Boat Deck Cleats 95 results of this test coincide in most respects with those of a similar cleat test conducted by a manufacturer several years ago. The Aluminum Boat Deck Cleats 95 cleat assemblies withstood simple tension loads of between 1, and 7, lbs. The lower figure is roughly equivalent to the load a ft. The cleat assemblies failed in one of four ways: fasteners, feet, legs, or the body of the cleat. Because fastener Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 failure predominated, it may be inaccurate to assess cleat strength based solely on the loads applied.
When the four loads each assembly withstood before failure are averaged, the stainless steel aluminum boat deck cleats 95 assembly withstood the greatest loads, followed by the four-hole hollow marinium cleat. Not surprisingly, aluminum boat deck cleats 95 nylon cleat ranked last, but it was stronger than we expected � Aluminum Boat Deck Cleats 95 it took a respectable aluminum boat deck cleats 95, lbs.
The test revealed that cleat design is at least as important Aluminum Boat Deck Cleats 95 as cleat material in affecting what breaks, and at what loads. Four-hole cleats were more aluminum boat deck cleats 95 to suffer Aluminum Boat Deck Cleats 95 failure of the feet, legs or body, while two-hole cleats suffered fastener failures 19 out of 20 times. We believe this is because the bolts in two-hole cleats are fastened directly through the center of the cleat, adding strength to aluminum boat deck cleats Aluminum Boat Deck Cleats 95 95 entire assembly.
It seems the load aluminum boat deck cleats 95 perpendicular to the axis of the bolts in two-hole cleats Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 causes the fasteners to shear off at the base. The feet failed consistently on half the four hole cleats, and they failed Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 under smaller loads than every other cleat except the hoat. Of these three four clears cleats with consistent foot failures, one was Aluminum Boat Deck Cleats 95 aluminum, one zinc and one Zamac.
Since these three metals have identical tensile strengths and held their own in the two-hole category, there had to be another explanation. We found the bozt in foot surface area: the three cleats with consistently failing aluminu, had Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 the three smallest foot surface areas of the six four-hole cleats we tested.
The feet on the aluminum-a big, beefy cleat failed Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 on all four pulls. The marinium cleat had no feet failures. It had twice the foot surface area of the aluminum cleat Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 0. So, we deduced, the design of the feetparticularly their surface area, is critical. Ironically, the weak-footed aluminum cleat was the most expensive of the 11 cleats we tested. Although stainless steel has the greatest tensile strength of a ll the cleat materials we Aluminum Boat Deck Cleats 95 tested double the tensile strength of aluminum, zinc, Zamac and mariniumit is nowhere near the most expensive cleat material, nor does it Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 necessarily produce the strongest cleat in a given application.
This is because, as mentioned earlier, a cleat is only one part of Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 a system, and that system is only as strong as its weakest link. Line is another part of the.
Chafe plays bozt Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 vital role in the security of any cleat. You can reduce chafe by using larger cleats, or cleats with smooth, round legs and no sharp angles, since the strength of a line is reduced by bending fatigue when it has to turn sharp corners Aluminum Boat Deck Cleats 95 or make tight bends.
Mount your chocks as close to the cleats as possible, and avoid changing the direction of the rope along its path through the chock to the cleat. As a rule, you should buy the largest size cleat your pocketbook and the deck space can handle. Choose one made of a high tensile strength material, like stainless steelbronze, aluminum or marinium.
Examine the Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 feet aluminu make sure they are large relative to the size of the cleat, sturdy, and have an ample thickness of metal Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 around the fastener holes. Marinium usually costs slightly more than aluminum. Both Aluminum Boat Deck Boxes Australia metals have the same tensile strength, but marinium has a Aluminum Boat Deck Cleats 95 higher strength-to-weight ratio. The marinium cleat held up dedk in our tests, performing almost as well as the stainless.
Zinc and nylon have the least tensile strength, and are the least expensive. But with zinc, as with aluminum and marinium, be aware of the potential for galvanic corrosion if you use fasteners of dissimilar metals like stainless in a saltwater environment.
Nylon or plastic cleats are fine for small boat rigging, flags and other low-load applications, but for moorings, docking, and ot her uses that involve the security of your boat, stick to the stronger devk To deck-mount a high-load fitting like a cleat so that it's really sound Aluminum Boat Deck Cleats 95 and water tight, first strengthen the system by reinforcing the base. Use an under-deck pad twice the length of the cleat and one half cleat length. Use only stainless steel or bronze bolts not screws as recommended by the manufacturer, and stainless washers under Cleats Boat Aluminum Deck 95 the nuts to spread the load.
Avoid locating cleats on soft-core surfaces like balsa-core. If it 's unavoidable, then aluminum boat deck Aluminum Boat Deck Cleats 95 Aluminum Boat Deck Cleats 95 cleats 95 core material must be removed and reinforced before installation, a job that's generally best left to a professional.
