Through Bolts
Metro Fixings provide a comprehensive range of Through Bolts from trusted brands like ITW Construction Products with their Spit range, Rawlplug, Fischer Fixings and JCP.
Through Bolts are a mechanical anchor that can be used in a wide variety of applications in concrete of 20N/mm2 and over. Through bolts are available in multiple sizes and materials including steel zinc plate and stainless steel.
Through Bolts carry varying levels of certification governed by European Technical Approval. The higher the ETA approval, the higher the performance of the mechanical anchor, for cracked concrete you would use an ETA Option 1 but for an application that has less stressful conditions a lower approval rating is suitable like ETA Option 7.
