Timco M20 x 130mm Zinc-Plated Throughbolts (10-Pack)
Timco's zinc-plated M20 throughbolts (130mm) for concrete anchoring. Grade 5.8 carbon steel with expansion clip for rapid installation.
The Timco Throughbolts offer a versatile, torque-controlled fixing solution for anchoring applications in concrete structures. Constructed from cold-formed carbon steel (grade 5.8), these bolts are zinc plated and passivated (3-5 microns) to resist corrosion and provide long-lasting durability.
Key features include a chamfered head design that prevents thread damage during installation, a special expansion clip for rapid fitting, and a complete set with hex full nut and washer for immediate use. The torque-controlled design ensures reliable fastening - if no torque wrench is available, simply tighten the nut 3 to 4 full turns from finger tight for optimal performance.
Ideal for professional builders and DIY enthusiasts, these throughbolts combine structural integrity with ease of installation. The zinc plating offers protection against the elements, making them suitable for both indoor and outdoor applications where a high-strength concrete fixing is required.
