• Dry indoor machinery, tooling and equipment
• Cup point screws grip on the shaft surface
• There are 46 items with diameters from M3 to M20 and lengths from 5mm to 60mm, so work out the size you need first and then read across the table.

Choosing the finish

Plain steel carries no protective coating apart from a light oil film, which is why it rusts quickly if it gets wet.

Keep plain parts for dry indoor use, machinery and assemblies that get painted, oiled or enclosed. Outdoors or in damp areas, a hot dip galvanised or 316 stainless alternative is the better choice.

In tooling and machine building, plain alloy socket screws are the usual choice, where the assemblies are usually oiled or enclosed.

Thread and strength

For load-critical, structural or lifting joints, confirm the fastener against the engineer's specification. Fasteners are not lifting rated unless marked.

Key specifications

Selecting the right option

Select socket set (grub) screws by thread form, diameter and length, and match the point type (cup point, flat point or cone point) to what the screw has to grip or locate on.
