The Most Common Method To Check The Connection Bolts For. The following definitions apply to the anchor bolt tightening procedure: Double-Nut Anchor Bolt System. An anchor bolt with 2 nuts that sandwich the structure’s base plate. The bottom nut is positioned under the base plate to level, support, and provide the reaction for the force applied by tightening the top nut positioned above the base plate., bolt (torque) at some point causes it to stretch (tension). Several factors affect how much tension occurs when a given amount of tightening torque is applied. The first factor is the bolt's diameter. It takes more force to tighten a 3/4-10 bolt than to tighten a 318-16 bolt because it is larger in diameter. The second factor is the bolt's grade..

  • Jun 01, 2006В В· A bolt is just a threaded fastener with a thread that does not extend all the way to the head, designed for use with a nut. But tightening the bolt correctly is a complex undertaking that requires understanding the characteristics of the bolted joint and the various tightening methods. Without a working load, the bolt is merely a clamping device. Inspection test should be within 24 hours of bolt tightening to prevent possible loss of lubrication or corrosion influence on tightening torque. Galvanized and A490 bolts can not be reused.
