1 4 Bolt Torque Value
In addition a proper bolt torque value can be inconsistent from fastener to fastener due to several factors including variations in material coatings surface finishes fit tolerances installation method etc.
1 4 bolt torque value. 1 can be rearranged to express bolt force as. Grade 2 grade 5 grade 8 18 8 s s bronze brass. Values calculated using industry accepted formula t kdp where t torque k torque coefficient dimensionless d nominal diameter inches p bolt clamp load lb. Pressure wax as supplied on high strength nuts 10 hot dip galvanized 25 and plain non plated bolts as received 20.
Coarse fine coarse fine coarse fine coarse fine coarse fine coarse fine 4 5 2 4 8 4 3. The torque required to achieve this force with a dry bolt is calculated to 2022 nm. For these reasons it is not practical to provide a single bolt torque chart or formula that is accurate for all situations. F t k d 1 l 100 1a example dry vs.
