Grainger Threaded Brass Insert - M4 - Bulk Pack

The Grainger double ended insert is a self-tapping insert. It has a coarse external thread form, with three equidistant cutting flutes and increased outside diameter and length.  These inserts are designed for use in wood and provide a secure mechanical connection without stressing the wood, particularly good where extra rigidity is required or the need to assemble and did-assemble the joint and on frequent basis

Please refer to the installation drawing above for the drilling specifications to suit our threaded inserts

This insert has an M4 metric tapped hole x 10mm Long

Bulk pack quantities are 10, 25, 50, 100 & 200

M4 Neck screws better suit standard bolt on necks which use neck plates rather than individual ferrule washers

We recommend the use of our manual installation tool when fitting our threaded inserts for ease and speed, please look under the tooling section for more details
