Product Description

Installing wedge anchors can be completed in three easy steps. Wedge anchors can be used in solid concrete applications, are best suited for light to heavy duty fastening purposes, are available in diameters from 1/4" up to 1-1/4", and are available in standard zinc plated, hot dipped galvanized and stainless steel. To determine the minimum anchor length for your application, simply add the material thickness to the minimum embedment and add the thickness of the nut & washer.

Drill hole into concrete

Insert wedge anchor into hole

Tighten the nut to desired torque

Drill and clean

Drill a hole in the concrete at least 1/2" deeper than the wedge anchor embedment using a hammer drill and a correctly sized carbide tipped bit. (Hole size is wedge anchor size).

Clean out the hole of all debris.

Insert wedge anchor

Place the nut on the end of the wedge anchor (to protect the threads of the wedge anchor during installation).

Hammer the wedge anchor into the hole deep enough so that the threads are below the surface of the base material.

Tighten the nut

Tighten the nut - torque to the appropriate foot pounds

Awesome plug & play bolts
5 Stars
Awesome plug & play bolts
Used these bolts for my shed project. Concrete slab (4,000 psi) with wood framing. Followed instructions on the box (just for drill bit size) and had no issues at all to insert them into the drilled holes and tighten them to give the bottom plates a strong hold to the slab. Framing is solid as a rock. Would buy them again for any other future project.
