Tension Control Bolts

For example Heat analysis C 0. F Grade F Chemical Properties. When coated, the same requirements of A and this specification, and Annex A1, including overtap, coating, rotational capacity and proof load testing apply. The auditor is due to arrive on the 21st of this month. F Grade 1 of this coating meets the supplementary lubrication requirements of A S1. Florida West Coast – Section Not logged in American Welding Society Forum.

ASTM F vs. F TC Bolts

Other Lenghts could be available upon request. The nut and washer shall be depressed.

By HgTX Date E Grade 5 of this coating meets the supplementary lubrication requirements of A S1. E Type 3 bolts conforming to Table 2, or Type 3 bolts which have a copper minimum Heat Analysis of 0. D Other distinguishing markings for type 3 are permitted at the manufacturers option. North Florida – Section Others coatings are typically applied after nut tapping. F is a TC bolt made to an A aztm.

ASTM F – Portland Bolt

Powered by mwForum 2. I think it answers your question. Proof Load D Min. By jwright Date Proof Load C Min. The chemical composition of the tension control bolts, nuts, and washers shall conform to the requirements specified. ASTM F has remained unchanged since For lots on which both hardness and tension tests are performed, acceptance based on tensile requirements shall take precedence in the event of low hardness readings.


This specification covers two types of heat treated, steel, tension control bolt-nut-washer assemblies, also referred to as “sets,” having a tensile strength of to ksi. The real weight may slightly differ from what is shown here. D Steel, as defined by the American Iron and Steel Institute, shall be considered to be alloy when the maximum of the range given for the content of alloying elements exceeds one or more of the following limits: Nevada awtm Section By eekpod Date Back To Home Page.

Does that mean since it was originally approved inand now its more than two years later that F is no longer an approved alternate? X Bearing-type connection with threads excluded from the shear plane. C Bolt pitch oversize limit in case of dispute.

Question, Whats the difference between F and F? Colorado – Section Material within the plain gauge limits which meets the coating thickness requirements and assembles freely need not be measured to this tolerance. Arizona – Section The table above is inspired by Table A1.

Superfast Fasteners India Pvt. By ziggy Date These assemblies are capable of developing a minimum sstm tension when installed by applying torque to the nut, while at the same time applying a counter torque to separate the spline end from the body of the bolt using an appropriate spline drive installation tool.
