M3 x 4mm Torx head shoulder bolt 316 black Stainless Steel A4

These Torx shoulder screws (similar to ISO10664) are manufactured of 316 Stainless Steel. Torx shoulder screws have an unthreaded "shoulder" and a multi pointed indentation in the fastener head.

Torx screws have a greater surface area of contact between the screw and the driver, which can reduce the likelihood of the screwdriver slipping or stripping the head.

Torx screws have a more secure fit than Phillips or slotted screws, which means they are less likely to strip or cam out under high torque applications.

Torx screws are often used in automated assembly because their design allows for quick and efficient engagement with the screwdriver.

Torx shoulder bolts are a popular choice for many applications where security, efficiency, and reliability are important considerations.

Shoulder screw applications can include bearings pins, die/punch works, pulley shafts or any shaft where accurate rotary movement is necessary.

These components are commonly used alongside eye bolts as a versatile mounting method.

Shoulder screws can be used in conjunction with:

Bearings: A shoulder screw provides a stable mounting point for bearings, which are used to reduce friction and support rotating components.

Pulleys and gears: The shoulder on a shoulder bolt can act as a precise and stable mounting point for pulleys and gears, allowing for accurate positioning and alignment.

Springs: The shoulder on a shoulder screw can provide a consistent and repeatable location for the end of a spring, which can be used to apply tension or compression to a component.

Bushings: Bushings can be used with shoulder screws to reduce friction and provide a stable mounting point for shafts or other rotating components.

Washers and spacers: These components can be used to provide additional support or spacing between the shoulder bolt and the component being mounted.
