Zinc Plated Steel Fine Pitch Nuts

Metric fine pitch nuts have more threads per unit length than a standard metric coarse pitch nut. For example M10 coarse pitch has one thread per 1.5mm and M10 fine pitch has one thread per 1.25mm.

Fine pitch nut and bolt assemblies are stronger than the equivalent coarse pitch assembly and are more resistant to loosening, when subject to vibration.

Fine pitch nuts are, however, more succeptable to damage and are more likely to suffer from thread galling. Consequently fine pitch components require more time to assemble.

This page features our current range of metric fine pitch nuts.

Thin Nyloc Nuts with Fine Pitch (Type T) DIN 985 in Bright Zinc Plated (BZP) Steel

These fine pitch metric nyloc nuts are manufactured to DIN 985 and are the low Type T. Nylocs are also known as prevailing torque or locking nuts. As they are tightened onto a bolt, the bolt will cut a thread into the nylon part, making it less likely to loosen. The fine pitch means that there are more threads per centimetre, giving more engagement and adjustability to the fixing. They need to be used in conjunction with the same pitch bolt. Typically fitted with a spanner or ratchet with socket. We recommend that anti-galling measures are taken on installation of stainless steel variants of these items.
