Technifast offer a selection of knurled nuts from M3 to M8 sizes, in stainless steel material. Knurled nuts (or thumb nuts as they are also known) offer a simple solution for light duty applications and provide a secure solution in many industries. Manufactured from stainless steel to offer greater resistance to corrosion, they have a straight-knurled outside surface which allows the nut to be gripped or tightened by hand, with metric internal threads.

We can offer discounts of up to 60% on volume orders of knurled nuts, please contact us for more information and a no-obligation, free quote.
