For purposes of uniformity in clamp loading, the calculations for the recommended installationtorques listed below are based upon K = for uncoated screws and K = for blue coatedscrews. Testing by reputable FASTENER manufacturers has proven that the use of split lockwashers underheads of hardened screws may prevent achieving or retaining the desired preload in bolted PROCEDURE1. Use only new fasteners for first-time Before installing the FASTENER , be sure that it is free of flaws and it is the correct property with flaws shall be marked with a white line drawn across the threads and Fasteners may be tightened with any appropriate fastening device. Final torquing shall be donewith a calibrated torque wrench to the required value as follows:4.

7 After torquing is completed, draw a straight line (match mark) from the wall of the FASTENER headonto the seating surface using a white steel paint pen. Ensure that the line is easily visible forperiodic A FASTENER suspected of being over-torqued shall be marked as described in item 2 and Do not torque fasteners at machine break points until final Where safety wiring is specified, do not safety wire any screws until they have passed the torque If fasteners are in a position that a torque wrench cannot be used, the following steps shall be used:a) Tighten the FASTENER until the joint surfaces have established a snug ) Mark the position of the FASTENER to the surface with a white steel paint ) Tighten the FASTENER 1/3 of a turn (120).d) After torquing is completed, draw a straight line (match mark) from the wall of the FASTENER headonto the seating surface using a white steel paint pen.

Ensure that the line iseasily visible for periodic all of the fasteners in the sample pass the audit, the data sheet shall be marked to so If one of the fasteners in the audit fails the audit:a. All fasteners of that type/size/property class shall be re-tightened. (Fasteners that passed theaudit may be excluded.)b. A new sample shall be selected for re-auditing using the criteria in No.

Bench Build Audit: Every unit shall pass the audit before it may leave the bench. Multipleunits may be combined to achieve the sample size of thirty Unit-to-Base Audit: Audits shall be performed at periodic stages of the assembly process toensure that any possible failures are corrected and passing audits are achieved whileensuring accessibility to all Final Audit: The final audit shall be performed after all engineering changes have been madeand all adjustments are complete. Applies only to screws installed per the NAAMS FASTENER Installation and Torquing Procedure. The method for checking the FASTENER torque is the Static Torque Method, which is defined as thetorque required to start a previously t ightened FASTENER into motion in the direction of t ightening.
