Proper torque spec varies depending on the material bolt grade or if lubrication is used such as oil wax or anti seize Always go to the manufacturer for proper torque specifications The chart above is an approximate estimate of torque values and have not been validated for accuracy
SAE J429 conforming bolts will have radial markings machined on the head of the bolt that indicate bolt grade A grade 2 bolt has no markings a grade 5 bolt will have three markings while a grade 8 bolt will have six lines Metric bolts are more simply identified the class is explicitly stamped on the bolt head
Never replace a graded hex bolt with a lower grade or lower strength do not substitute a stainless steel or silicon bronze bolt for a Grade 5 or 8 bolt or a brass bolt for a Grade 2 5 or 8 bolt Head markings identify the grades A307 is usually identified as 307A or 307B no lines is Grade 2 three radial lines 120 176 apart identifies the
Oct 16 2007 nbsp 0183 32 Torque is simply a measure of the twisting force required to spin the nut up along the threads of a bolt whereas tension is the stretch or elongation of a bolt that provides the clamping force of a joint Bolts are designed to stretch just a tiny bit and this elongation is what clamps the joint together
2 days ago nbsp 0183 32 Bolt Grade Markings Grade identification marks are created and appear on the head of the bolt and are used to designate their grade For commonly used ASTM and SAE steel grades there are grade identification tables that designate these markings and specify the minimum acceptable values of proof tensile and yield strength that are required to
