The Carbon Steel Wedge-Bolt OT screw anchor is a specifically engineered part for the racking industry. This unique and universal anchor is available in a finished hex head design and can be easily installed with either an impact wrench or conventional hand socket. This anchor, unlike Blue tip Wedge-Bolt, can be installed with regular ANSI standard carbide drill bits with larger clearance holes.
(4) Stainless Steel Hex Head The 316 SS Wedge-Bolt screw anchor is specifically engineered for exterior applications where high corrosion resistance is needed, withstanding the most demanding conditions. With the corrosive resistant properties of 316 SS, the anchor can be used in waste and water treatment plants, food and beverage facilities and marine applications. This anchor can be easily installed with either an impact wrench or conventional hand socket.
(7) Stainless Steel Hex Head The 410 SS Wedge-Boll screw anchor is specifically engineered for exterior applications where corrosion resistance is needed. Applications may include coastal areas, exterior metal lighting, industrial applications, screen enclosures and storm shudders. This anchor can be easily installed with either an impact wrench or conventional hand socket.
The Tapper™ Anchoring System is a family of screw anchors, specially designed drill bits and installation tools designed to meet the needs of most light to medium duty applications in concrete, block and brick. The Tapper™ concrete screw anchor is produced in either Hex washer head or Phillips flat head styles from Perma-Seal™ coated or zinc plated carbon steel and Type 304 stainless steel. For heavy duty applications, the 3/8" size is made in zinc plated carbon steel.
Tapper™ Drill Bits in the diameters listed are nominal size. 3/16" and 1/4" Perma-Seal™ Tapper™ anchors must be installed with special tolerance Tapper™ drill bits. 1/4" Stainless Steel Tapper™ anchors require the use of specific tolerance Tapper™ drill bits, which are gold or silver colored, to denote the standard size and special application size for harder materials. 3/8" diameter Tapper™ anchors should be installed with a 1/4" ANSI drill bit.
