M3 x 6 mm Cheese Head Slotted Machine Screw, 316 Stainless Steel - CHSA4M3X6

The Cheese Head Slotted Machine Screw, 316 Stainless Steel is a machine-thread screw with a cylindrical (cheese) head and a single slot. It screws into a nut or tapped hole.

This listing has 50 variants covering sizes M3 to M8 and lengths 6 mm to 50 mm. Each variant is supplied in packs of 100.

Supplied in 316 (A4) stainless steel. The molybdenum in A4 gives better resistance to chlorides than A2 (304), so it is the usual choice near the coast, around pools and in marine and food-processing environments. Metric sizes are written M followed by the nominal thread diameter in millimetres, so M10 is a 10 mm thread.

Austenitic stainless steel is generally non-magnetic, although cold-worked parts can show weak magnetism. Use stainless washers and nuts with stainless fasteners, so the whole joint is made of the same material.

Key specifications

Selecting the right option

Use a flat-blade driver that fills the full slot width to avoid damaging the head. Where a higher drive torque is needed, a hex socket or Torx head is a better choice.
