Hex Head Bolt and Large Washer in Black Zinc
Our combination of hex head bolt and large washer with a black zinc finish delivers rugged performance with a clean, unified look. The black zinc plating provides dependable baseline corrosion protection, while the oversized washer spreads bearing pressure, protects surfaces and reduces indentation—especially on softer materials or slotted-hole joints.
Benefits & Applications
Typical uses include metal and timber joints, shopfitting and trade-fair builds, machinery, automotive (body/interior), furniture, and visible architectural/interior projects. The hex head enables secure tightening with a spanner or socket; precision threads support consistent torque and repeatable clamping force.
- Black zinc finish: sleek, uniform look with base corrosion protection
- Oversized washer: improved load distribution and fewer settlement effects
- High operational reliability from the bolt + washer pairing
