Hex Bolts A Complete Guide RS Components
2023年8月29日 Hex bolts are a type of threaded bolt, characterised by their sixsided hexagonalshaped head Hex bolts can be either fully threaded or partially threaded (featuring a clear shank along part of the body) and are suitable for The hexagonal head provides the necessary torque for tightening, and the threaded shaft and nut interaction prevents the connection from loosening over time Applications of Hex Bolts Hex bolts find application in a myriad of industries and projects, Even though hexagonal bolts from a wide range of material options are available, What is a Hex Bolt? Its Types, Sizes, Working, ApplicationsThe torque figures quoted have been based on a theoretical bolt load equal to 85% of the proof load of the bolting material Where the proof load is not quoted in the specification this has been taken as 95% of the yield stress Metric Bolting Diameter Tensile Stress Area mm² Suggested Bolt Load KN Approximate Torque Nm Grade 46 88 109 129Torque Settings Grampian FastenersNEW Carbon steel Hexagonal Head HolloBolts have been independently evaluated for fatigue resistance per AISC 360 Appendix 3; NEW Carbon steel Hexagonal Head HolloBolts have been independently fire tested per ASTM E119*; Code compliant with IBC, IRC, CBC, CRC, LABC, LARC, ADIBC; Fast, cost saving installation from one side For square, rectangular and Lindapter Type HB HolloBolt Hexagonal Head Expansion Bolt
