2.5 inch long thread rolling (thread forming) screw 

The Hex Washer Head has a flat washer that extends beyond the sides, providing it with a greater bearing surface than a normal hex head fastener. The washer and the Hex Head are bonded together as one piece; this offers greater protection to the mating surface than a standard 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, retards the corrosion rate in a normal atmosphere.

This is a 0.5 in. Hex output shaft with a 57 Sport mounting. We suggest using our red tacky grease, am-2768. We encourage that the user powers the gearbox continuously for 30 minutes without grease to allow the gear teeth to wear in. While we do design with short run times in mind, this 'run in' period for smooth gearbox operation, is recommended. Once this is completed, thoroughly grease the gear teeth periodically to ensure smooth operation.

The LJ Bevel Box is a right angle gearbox using steel bevel gears, designed to integrate with a CIM Motor (am-0255), CIM-Sim (am-0932), 57 Sport, or CIM Sport. This setup allows for the use of a gearbox or CIM motor in locations where you many not have the space available for an assembly in a straight line. We recommend using this gearbox in low torque setups. An E4T encoder can be added to the side of this gearbox, but is not included.

Snap action breakers are used commonly in mobile robot applications such as FIRST Robotics Competition power distribution boards. We offer several amperage versions.
