Macsim 3/8" x 6" Cup Head Coach Bolt and Nut Zinc Plated

A loose join is the thing that comes back to bite you, so the fixings have to hold. This Macsim coach bolt and nut is built for solid structural work, holding timber to timber and metal to metal in framing, post supports, fencing and retaining walls.

It has the classic cup head, a smooth domed top over a square neck that bites into the timber as you tighten, so the bolt will not spin while you do up the nut. The 3/8" thread runs 6" long, and the whole thing is grade 4.6 with a zinc-plated finish that keeps the rust at bay for general outdoor use.

Sizing is imperial, so match it to what you are replacing or bring the old one in and we will sort the fit. If you need a box or a bulk run for a bigger job, give us a call and we will price it up.
