3/4 x 4 3/4 Alloy Steel Socket Head Shoulder Screw (Stripper Bolt) with Nylon Insert is designed for assemblies requiring a shoulder screw that can fasten while also serving as a guide, pivot, or spacer. The shoulder screw design separates the functional bearing or locating surface from the threaded retention point. Typical applications include assembly equipment, pivoting components, locating nests, and serviceable machine designs. For maintenance teams, the nylon insert can help address loosening concerns in equipment subject to vibration or repeated motion. Machine builders can use the internal hex drive and shoulder geometry in compact assemblies that still require service access. Selection should follow the required shoulder diameter, shoulder length, material, and assembly function shown for the part. It is appropriate for buyers comparing shoulder screws by exact shoulder diameter, shoulder length, material, and insert feature.
