1/4 x 4 3/4 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert provides a defined shoulder for controlled movement, accurate positioning, and serviceable fixture design. The important engineering feature is the shoulder, which supports positioning and movement while the threaded end retains the fastener. Typical applications include conveyor equipment, assembly fixtures, spacer locations, and controlled-travel mechanisms. The insert feature gives buyers a nylon-insert shoulder screw option for applications where retention matters alongside guided movement. Repair technicians may source this part for replacement applications where motion control and retention both matter. Alloy steel construction supports industrial fastening applications where the shoulder performs the working role in the assembly. Common sourcing contexts include replacement maintenance, fixture construction, and OEM production support.
