The reduced torque can be calculated, Eq. Typical values for K with mild-steel bolts in range 1/4" to 1": Note! Maximum Torque Guide - Stainless Steel in Nm. Examine parts after the test ride to ensure all parts are secure.
Torque for Flanged Hex Head and Tapered Socket Cap Bolts - use torque values specified by your equipment manufacturer.
Boltmasters Pty Ltd Recommended Assembly Torques. Use manufacturer’s original seals in conjunction with seal supplied by Pro-Bolt. Pro-Bolt offer a variety of products in three different materials, each offering a different level of strength suitable for different applications. We replicate the dimensions of manufacturer’s original parts and this often results in bolts with a low head profile, therefore a small and shallow drive.
Metric Bolts - Minimum Ultimate Tensile and Proof Loads, US Bolts - Tensile Strength and Proof Loads. The calculator is generic an can used for imperial and metric units as long as the use of units are consistent. If used in conjunction with a steering damper, it is essential to check that the steering is not affected.

Some of our calculators and applications let you save application data to your local computer. Cookies are only used in the browser to improve user experience. Lubricating the bolts is the suggested method. By failure the bolt is lubricated and tightened with the same torque 2022 Nm. Please adhere to the following guide at all times: Do not use aluminium bolts in any stress areas e.g. By failure the bolt is lubricated and tightened with the same torque 2022 Nm. Torque Table Standard Bolt Sizes … The torque required for a 3/4" dry steel bolt with 0% lubrication to achieve this tension can be calculated as, Tdry = (0.2) (20000 lb) (0.75 in) (1/12 ft/in) (1 - (0%) / (100%)), The proof load for a M30 metric bolt grad 8.8 is 337000 N. The torque required to achieve this tension with a dry bolt with 0% lubrication can be calculated as, Tdry = (0.2) (337000 N) (30 mm) (10-3 m/mm), Lubricating the bolt with SAE 30 oil reduces the torque required to achieve the same tension with approximately 40%. Do not use if any contact is detected. Pre-Load Adjusters: Pre-Load adjusters are for use with standard fittings. To avoid a potential snapping of the thread, ensure an even purchase when fitting.
