Anchor Bolts

Non Chemical Anchor Bolts: Choose a drill bit which matches the outside diameter of the anchors sleeve, be sure the drill bit is not worn as it may no longer be the appropriate size. Holes should be drilled deeper than the length of the anchor bolt and any dust cleared away from the hole before removing the drill bit. In order to provide the grip required for tightening, the anchor should fit snug into hole with a minimal amount of force. If the hole is too small, do not attempt to use force as the bolt may be damaged and become lodged in an insecure manner. Instead, remove the bolt and select a more appropriate drill bit. Bolts which fail installation should be treated as damaged and discarded as a precaution against failure. If the hole is too large, the bolt will not tighten or be loose and prone to failure. If this is the case, the hole should be relocated or a larger anchor bolt installed. The exact tightening method will depend on the type of anchor bolt you have chosen to use.
