RS PRO Stainless Steel Self Locking Nuts Box, 545 Pieces

The RS PRO self-locking Nyloc nut set contains 545 nuts in seven different sizes from M3 to M10 (3 mm to 12 mm diameter hole). They're organised in a 9-compartment storage box, so you'll always be able to find the nut of the size you need. The nuts box is made of durable polypropylene, so it's sturdy enough for use in industrial or factory conditions.

Nyloc nuts have a nylon collar that increases friction on the screw thread to make them self-locking, so they won't come loose when they experience vibration from motors or contraction and expansion from heat or cold. They're made of A4 (316) stainless steel, so they can be used in harsh environments, such as marine settings. Highly abrasion-resistant, they can also withstand corrosive liquids or chemicals.

The nuts are suitable for use with ISO metric machine-threaded screws or bolts and accept standard metric spanners or sockets. Use them everywhere from home workshops to heavy industry.
