Shoulder Screws reduce rotation through locking
Alloy Steel is one of the strongest materials used in fasteners, making this an perfect material to use when the primary concern is the application pulling apart
Socket cap head fasteners are very common in industrial applications
Drive system is a hexagon-shaped hole
Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads
Shoulder Screws, also known as Shoulder Bolts, are used for several different applications, including those that involve rotation or require a locking type of screw. Shoulder Screws are distinct from other types of screws due to the fact that they are only partially threaded, leaving a smooth-sided round or square shaft between the threading and the head. This shaft is usually slightly larger than the threaded portion of the screw. Often used in automotive and mechanical applications.
With a high cylindrical head, socket cap head fasteners have a recessed driving area and offer high hold power at high torque levels. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits.
