The TIMCO Multi-Fix Bolts Hex Head Exterior Silver 16.0 x 150 provides a stress-free, non-expansion through fixing solution for heavy duty anchoring into concrete, brick, stone, wood and concrete block. These innovative bolts replace traditional anchors such as throughbolts, shield, sleeve and drop-in anchors with their unique concave thread configuration and high-low parallel threads for ease of insertion and high pull-out values. Featuring TIMco micro plating (Nano) technology for enhanced corrosion resistance, these removable and adjustable fixings conform to BS 7671 standard’s 18th edition requirements for fire safety, being all steel and non-flammable materials unlikely to prematurely collapse in the event of a fire.
