Power-Stud+ SD1 Wedge Expansion Anchor


Product Description

The Power-Stud+ SD1 anchor is a fully threaded, torque-controlled, wedge expansion anchor which is designed for consistent performance in cracked and uncracked concrete. Suitable base materials include normal-weight concrete, structural sand-lightweight concrete and concrete over steel deck. The anchor is manufactured with a zinc plated carbon steel body and expansion clip. Nut and washer are included.

General Applications and Uses

  • Structural connections, i.e., beam and column anchorage
  • Safety-related attachments
  • Interior applications / low level corrosion environment
  • Tension zone applications, i.e., cable trays and strut, pipe supports, fire sprinklers
  • Seismic and wind loading

Features and Benefits

  • Consistent performance in high and low strength concrete
  • Nominal drill bit size is the same as the anchor diameter
  • Anchor can be installed through standard fixture holes
  • Length ID code and identifying marking stamped on head of each anchor
  • Anchor design allows for follow-up expansion after setting under tensile loading
