Socket Head Shoulder Screws

Metric. BSW. BSF.

Shoulder screws, also known as shoulder bolts and stripper bolts, are machine screws with an integral shoulder or journal between the head and thread. Although they are not readily available in local hardware stores, shoulder screws are used extensively in industries from aerospace to consumer products because of their versatility and unique attributes when installed.
Shoulder screws have three main sections: head, shoulder, and thread. The head has the largest diameter, the shoulder is described by its diameter and length, and the thread has a major diameter slightly smaller than the shoulder diameter.
When the thread of the shoulder screw is fully installed, the unthreaded shoulder extends beyond the surface into which the thread embeds. The shoulders give the screws their versatility by acting as shafts or dowels for rotating items such as bearings and bushings, axles for rolling parts, guides for sliding elements, and pivot points or mounting pins.
These screws are also used to attach stripper plates.
A socket head shoulder screw  is most commonly driven with an allen wrench or hex key.
