Tie Down Accessories
When one is shopping for hardware, one must decide which type of hardware they are shopping for. Usually, hardware can be divided into two categories: end fitting and tensioning buckle. End fitting is a load bearing part that gets attached by being sewn to the synthetic webbing which then gets attached to tensioning buckles. End fitting has many different categories. Chain anchors, flat hooks, S hooks, wire hook, snap hooks, delta rings, d rings, E track fittings and specialty strap end hardware. The name flat hook and s hook come from the shape of the hardware. Wire hook is often called J hook or double J hook. Tensioning buckles can be divided into three different categories: cam buckle, overcenter buckles, and ratchet buckles. All hardware is for 1" to 4" tie-down strap application.
Hardware can be made of metal or any other acceptable material. They are attached to a web cargo tie down by being sewn with webbing for the application of securing the cargo. Hardware can be on fixed or adjustable end. It is important to note that the improper use of hardware can result in serious injury or death. The material of hardware for tie downs must be compatible with the mechanical requirements. The clean surface with smooth edges must be present to prevent possible cutting of the webbing. Additional coating for corrosion resistance is recommended. Safety factor of 3 is required to design the proper working load limit. Reuse of hardware is accepted upon the inspection. No visible wear, cracks, or break should be allowed when reused. Repair on hardware is prohibited. Proof loading test of hardware is done with 1.5 times the working load limit.
