Code listed for cracked and uncracked concrete, and masonry applications, the Strong-Bolt 2 wedge-type expansion anchor is an optimal choice for high-performance even in seismic and high-wind conditions. Dual undercutting embossments on each clip segment enable secondary expansion should a crack form and intersect the anchor location; this feature significantly increasesthe ability of Strong-Bolt 2 to carry load if the hole expands.
Specifications
- Diameter: 1/4″
- Length: 3-1/4″
- Drill Diameter: 1/4″
- Torque (concrete): 4 ft-lbs.
Installation
- Drill a hole in the base material using a carbide drill bit the same diameter as the nominal diameter of the anchor to be installed.
- Drill the hole to the specified embedment depth, and blow it clean using compressed air. (Overhead installations need not be blown clean.) Alternatively, drill the hole deep enough to accommodate embedment depth and the dust from drilling.
- Place the anchor in the fixture, and drive it into the hole until the washer and nut are tight against the fixture.
- Tighten to required installation torque.
