Through Bolts

Thru Bolts – Heavy-Duty Anchors for Concrete & Structural Fixing

Our thru bolts are high-performance mechanical anchors designed for strong, secure fastening into solid concrete and dense masonry. With an expanding sleeve and full-length threaded bolt, they deliver a tight, vibration-resistant hold, perfect for structural steel, base plates, railings, heavy machinery, and safety barriers.

Choose from 316 stainless steel for marine and corrosive environments, or hot-dip galvanised steel for tough outdoor and industrial applications. Thru bolts are ideal when you need through-fixing of materials directly into concrete with high load demands.
