Zinc Plated Throughbolts

Zinc-plated throughbolts available in a variety of sizes at great prices. Being zinc plated, the bolts can have a yellow-tinted passivation or more of a bright zinc passivation. Both offer the same level of resistance to corrosion. The through bolts are designed to fix timber to walls and concrete by passing through the material into the substrate and use friction and expansion to ensure a secure fixing. When tightened, the cone on the bolt is pulled into the shaft which causes expansion and fits the bolt in place.

A robust fixing for concrete with bulk discounts are available across the range.
