M5 X 25 slot head shoulder bolt 316 black Stainless Steel A4

These slot shoulder screws (also known as shoulder bolts) are manufactured of 316 Stainless Steel. Slot shoulder screws have an unthreaded "shoulder" and a single horizontal indentation (the slot) in the fastener head and can be tightened by a flat-bladed screwdriver.

The advantage of slot head bolts is that they can be easily driven with a simple flathead screwdriver. This makes them a good choice for applications where a specialized tool is not available or practical.

They are particularly useful in situations where the screw needs to be flush with the surface, such as in woodworking or cabinet making.

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.
