PtB-ProThroughbolt

ProDUCt DeSCriPtion

The PTb-PRo is a fully threaded, torque controlled, wedge expansion anchor which is designed for consistent performance in cracked and uncracked concrete. The anchor is easy to install and suitable for a variety of base materials. The wide range of available PTb-PRo anchor sizes covers all common capacity demands. The superior load-displacement response qualifies the PTb-PRo for both standard and adverse loading conditions.

General aPPliCationS anD USeS

featUreS anD BenefitS

•consistent performance in high and low strength concrete

•nominal drill bit size is same as the anchor diameter

•anchor can be installed through standard fixture holes

•fully threaded bolt for highest flexibility

•M12 and M16: two embedment depths approved for flexible fixture thicknesses

inStallation inStrUCtionS

1.) Using the proper drill bit size, drill a hole into the base material to the required depth.

2.) Remove dust and debris from the hole using a hand pump or compressed air.

3.) Drive the anchor into the hole at least to the minimum required embedment depth.

4.) Tighten the anchor with a torque wrench by applying the required installation torque Tinst.

for complete installation instructions, see technical approval.
