Collated screw models are designed for use with the Quik Drive® system. Privacy Policy. Now take this and multiply by the same 72,000 PSI and it results in approximately 21,740 pounds. b. Industry studies show that hardened fasteners can experience performance problems in wet or corrosive environments. %%EOF For design purposes, steel sheet thicknesses are 0.0283" for 27 mil, 0.0346" for 33 mil, 0.0451" for 43 mil, 0.0566" for 54 mil, 0.0713" for 68 mil, and 0.1017" for 97 mil. The actual preload will depend on how far the nut is turned as well as how much preload was established prior to the turning. RSS screws can be used as a lag screw alternative. 0 0000004792 00000 n The nominal strength values listed are achieved under laboratory conditions and should not be used for design loads. Screws must extend through the steel connection a minimum of 3 exposed threads per AISI General Provisions Standard Section D1.3. 0000003931 00000 n t´ Total thickness of fillers or shims (see Section 5.1), in. endstream endobj 16441 0 obj<>/Size 16406/Type/XRef>>stream 0000007255 00000 n Match mark bearing face of the nu… This includes thickness of all the members, including the gaps between them. Use the thickness of the member in contact with the screw head to determine Pull-Over value and the base member thickness (member not in contact with screw head) to determine the Pull-Out value. B. Bolted Connections a. The shear capacity of the bolt is given by . GRK 3/8 x 6-inch GRK RSS Rugged Structural Screws GRK RSS Rugged Structural Screw has a patented design and made of specially hardened steel to provide customers with high tensile, torque and shear strength.

Corrosion Information Guidelines for selecting the proper connector coatings and fasteners. Learn how our HeadLOK Flathead Structural Wood Screw is ideal for fastening a variety of wood applications. Currently, there are equations for predicting the nominal shear strength of a screw connection given in the American Iron and Steel Institute’s North American Specification for the Design of Cold-Formed Steel Structural Members. GRK Fasteners' RSS™ Rugged Structural Screw is made of specially hardened steel to provide you with the highest tensile, torque and shear strength available.
