PFG SB, SBS Anchor with Threaded Stud, Washer and Nut

The PFG SB, SBS anchor with threaded stud, washer and nut is a universal expansion anchor with a conical stud. It is the most strongly expanding anchor, suitable for installation in low-quality materials. PFG SB, SBS anchors are designed for heavy and medium-heavy fastenings in concrete, solid brick (max. M8) and natural stone. Diameter from M6 to M16, thickness of the material being fastened up to 85 mm. Stud anchor.

PFG SB, SBS anchor dimensions

SB = electro-galvanized, SBS = sherardized (sherardizing is a type of galvanizing process involving heating steel parts in zinc powder).
