Product description

This 1/4-20 x 3/8-inch Knurled Cup Point Setscrew is a high-strength industrial fastener designed for securing pulleys, gears, and collars to shafts within the mechanical assemblies of Snap-On automotive equipment. The knurled cup point is a specialized design that provides superior vibration resistance by biting into the shaft material, creating a more secure lock than standard flat-point setscrews. This is particularly important in high-torque or high-vibration applications like motor drives or pulley systems, where loose components could lead to mechanical failure or equipment downtime. Made from alloy steel and treated for durability, this setscrew ensures a permanent or semi-permanent fix that resists backing out under load. Its 1/4-20 thread pitch and 3/8-inch length make it a versatile and essential piece of hardware for precision maintenance and repair tasks across various shop tools and lift systems.
