A325 N and A325 X - Structural engineering general ...I understand that A325 N means threads are included in shear plain and A325 X means the threads are not included in shear plane. My question is when would you want to have the threads in the shear plane? Doesnt that effect the connections strength?

to the bolt type versus that of the connection type. The A325 example refers to the bolt type, while the SC or N refers to required installation details for the connection type and geometry respectively. Bolt Types The most common types of bolts used in structural steel appli-cations meet either the ASTM A325 or A490 Standard. ThereWhat is A325 structural bolt?A325 and A490 structural bolts are specialized, heavy hex bolts designed to withstand the loads of steel-to-steel connections. The head of the heavy hex structural bolt is specified to be the same size as the heavy hex nut of the name nominal diameter, allowing a single size wrench or socket to be used on the bolt head and nut.See all results for this questionWhat does X mean on A325?X means these particular A325 heavy hex structural bolts will be used in a bearing type connection where the threads will be excluded from the shear plane, whereas N means the threads are included in the shear plane.See all results for this question

The actual preload will depend on how far the nut is turned as well as how much preload was established prior to the turning. 1. Snug the joint to bring the assembly into firm contact. Apply a few impacts with impact wrench until solid sound or apply full effort with a spud wrench. 2. Inspect the joint to verify "snug tight". 3.

Can black A325 bolts be reused?

When approved by the Engineer of Record, black ASTM A325 bolts are permitted to be reused. Touching up or re-tightening bolts that may have been loosened by the installation of adjacent bolts shall not be considered to be a reuse.See all results for this questionAre ASTM A325 bolts the same as SAE J429?Answer: No. The strength properties of SAE J429 grade 5 bolts and ASTM A325 bolts are identical; likewise, SAE J429 grade 8 bolts are the strength equivalent of ASTM A490 bolts. These material specifications differ, however, in that ASTM A325 and A490 specify thread length and head size, whereas SAE J429 does not.See all results for this questionASTM A325 - Lord & Sons, Inc.The ASTM A325 specification covers high strength heavy hex structural bolts from 1/2 diameter through 1-1/2 diameter. These bolts are intended for use in structural connections and therefore have shorter thread lengths than standard hex bolts.
