Hobson NN08YCM08 M8 Nyloc Hex Nut, Class 8, Zinc Yellow Passivate

A nyloc nut is a hex nut with a nylon ring fitted in its top face. The nylon ring is the locking feature of the nut. This page lists 3 Hobson metric nyloc hex nuts (metric thread, Class 8, zinc yellow passivate finish): M8 to M18.

The supplier names these nuts Class 8. The Hobson strength tables cover bolts, not nuts, so no strength figures are published for these nuts.

The Hobson High Tensile Stock List, April 2011, names DIN 985 in its heading for these nuts (manufacturer-stated).

Pitch is the coarse pitch for each diameter from the Hobson thread table (manufacturer-stated). The supplier descriptions do not state a pitch.

Catalogue pack weights are from the Hobson High Tensile Stock List, April 2011, and are shown only where the catalogue pack quantity matches the pack quantity here (manufacturer-stated).

The pack, box or bag quantity for each size is shown in the table.

Common specifications

Key specifications

Selecting the right option

Match the nut to the bolt, stud or rod: thread form, diameter and pitch must all agree. Sizes are the nominal thread diameter in millimetres; compare the pitch with your bolt. Check the supplier details if your application has a temperature or chemical limit, because this page gives no limits for the nylon ring. Choose the class or grade to suit the bolt you are fastening, and confirm the pairing with your specification if the joint is load-critical.
