This is a Trilobe, thread forming, or thread rolling screw, ideal for applications where the screw is being threaded into plastic or metal. 

A flat washer is part of the 5/16 hex head, providing more surface area contact than a regular hex head. The increased bearing area decreases the likeliness of crushing mating surfaces. Trilobe, or Thread Rolling, screws have a blunt tapered point that requires a pre-drilled or punched hole; eliminates chips and permits replacement with standard screw. Zinc plating froms a zinc carbonate film that greatly retards the corrosion rate in a normal atmosphere, which is similar to the aluminum oxide film that forms on aluminum that accounts for its low corrosion rate.

This Inline Chain Tensioner for #25 series roller chain is perfect to adjust the desired tension in a long run of chain on mechanisms such as elevators and arms. This is ideal where there is at least a ~3" section of chain that never passes over a sprocket in a given mechanism. Pair this with two #25 Master Links and integrate this to your project for an easy-to-use chain tension solution!

The design of this product was inspired by Misumi's Chain Turnbuckles. This product has been improved to be compatible with imperial-sized wrenches.
