NUTS - BONDABLE bigHead® HEX NUTS - Round Base

Product Description

The bigHead® Hex Nut is a bondable hex nut attached to a galvanized or stainless steel head. They are available in different standard sizes and head shapes, to suit your specific application needs. These bondable Hex Nuts are available with or without a sighted center hole, and may be customized to suit your application needs. Their large perforated "head" provides an invisible, molded-in fastener, fixed for life, with very high torque and shear resistance.

Features & Benefits

bigHead® fasteners are used extensively in many industries including plastics, auto, engineering, and increasingly in construction, building and other fields. They can be molded-in during manufacture, riveted, screwed, or spot welded. With the advent of modern adhesives providing permanent bonding, designers and manufacturers can specify bigHeads® for "blind" application to almost any surface or material.

*These fasteners are supplied with self-adhesive masking dots.
