Find online torque specification charts for bolts on sites such as PortlandBolt.com, EngineersHandbook.com, BoltDepot.com, RepairEngineering.com and EngineersEdge.com. The charts on these sites contain information about torque requirements based on bolt size, the coarseness of bold threads and the type of metal used in the bolt.
The torque chart on PortlandBolt.com is organized based primarily on the bolt size, then on factors such as threads per inch and load capacity. It also features charts for different measurement types of bolts, whereas most other sites offer only charts based on standard U.S. bolt sizes. Some sites also offer additional information about the different types of fasteners used with the bolts.
