Torque Values Stainless Steel Bolt Table Chart - Engineers Edge
Torque Values Stainless Steel Bolt Table Chart. Recommended Bolt Torque Values for Stainless Steel and Nonferrous Fasteners (inch series). The following torque values are suggested maximums based upon actual lab testing on clean and dry or near dry fasteners.
Torque Values for Stainless Steel and Non-Ferrous Fasteners. Suggested Maximum Torquing Values - a guide based upon actual lab testing on dry or near dry fasteners wiped clean.
The recommended steps are, Construct at least 10 assemblies of the application joint. Using a calibrated torque wrench, tighten the bolts or machine screws until failure and record the maximum torque achieved in each failure. Calculate the average torque from the tests.
Use Prevailing Torque All-Metal Nut chart if using this style of nut. = Nominal Diameter. = Clamp Load For J429 Grade 5 and 8, FNL Grade 9, A574, Class 4.6, 8.8, 10.9 and 12.9, the clamp loads are listed at 75% of the proof loads specified by the …
ASTM A193/A193M B8 and B8M Class 1 Torque-Tension Guide. Caution: Stainless steel fasteners tend to gall, especially with long run downs, prevailing torque fasteners, impact drivers, and lack of lubrication.
Tightening torques for stainless steel bolts - BSSA
Minimum breaking torque, (M B, min), for austenitic grade bolts and screws between M 1.6 and M 16, (coarse threads), are shown in Table 8 of BS EN ISO 3506-1:2020. This shows torque values in Nm for property classes 50, 70 and 80 as shown in the table below.
Values given represent the torque required to induce a tension in the bolt corresponding to approximately 65% of its proof load. * This table is recommended for use as a guide only. While all care has been taken with its preparation, no responsibility is accepted for the
Stainless Steel Hex Cap Screw (ASTM F593) & Socket Head Cap Screw (ASTM F837) Torque-Tension Guide. Caution: Stainless steel fasteners tend to gall, especially with long run downs, prevailing torque fasteners, impact drivers, and lack of lubrication.
The torque values can only be achieved if nut (or tapped hole) has a proof load greater than or equal to the bolt's minimum ultimate tensile strength. Torque values calculated from formula T=KDF, where Lubricated Clamp Load F based on 75% of Yield Dry Clamp Load F based on 40% of Yield to avoid Galling. K = 0.16 for "lubricated" conditions
