An old rule-of-thumb³ is that in a threaded hole in steel, the length of engagement should be at least 1.5 times the diameter of the screw, and in cast iron or brass, 1.8 to 2 times the diameter. Blind holes should be at least half a diameter deeper than the length of engagement. 1. ANSI B18.6.3-1972 (R1991) WebTo optimise a bolted joint, it is recommended to design the clamped length to at least 3 or 5 times the bolt diameter. Increasing the elasticity of the fastener greatly improves the properties of the joint, as it: Increases the elongation of the bolt, reducing settlement effect. efg hermes egypt financial statements

Web1 jun. 2024 · About 60% of the load is carried by the first 3 threads, so you can usually get away with a smaller thickness than the bolt diameter if necessary. If you aimed for a minimum of 5 threads engaged this would be pretty safe in most cases. You could factor this based on the ratio of yield strengths between the fastener and plate if concerned. Web4 okt. 2024 · Thread Engagement Length Calculator Bolt Length Formula The following formula is used to calculate a bolt length. BL = (D*2) + ( a + b + c...) B L = (D ∗ 2) + (a + b + c...)
