M8 Shear nuts ART. 9305 A2 200 pcs.

Shear nuts M8 A2 — 200 pieces

The nut consists of a round part with a widening profile, a reduced section and a hexagon for tightening. During installation, the hexagonal part breaks off at the reduced section. The round part remains on the joint, making removal with an ordinary spanner difficult.

Material and application

Made from stainless steel A2. The nuts are intended for permanent security joints, including fencing, signs and boards, and street furniture. Breaking off the hexagon limits access to the spanner flats; it does not make removal by specialist methods completely impossible.

Scope of supply and installation

The price includes 200 M8 A2 nuts. The carton graphic is a neutral illustration; the number of visible items does not determine the quantity supplied or the factory packaging method.
