The ASTM F Grade F, (Also known as A TC bolts) specification cover heat treated, steel, tension control bolt-nut-washer assemblies, also referred. Round Head Tension Control Structural Bolt Assembly, ASTM F, Type 1,. Plain. The information below lists the required dimensional. This specification is a consolidation of and replacement for six ASTM standards: A, AM, A, AM, F and F The main.

Specifications Types of F Bolts. C Previously used markings may be sold and used indefinitely, bolts must be manufactured to current marking requirements upon initial publication of this standard. D Other distinguishing markings for type 3 are permitted at the manufacturers option.

ASTM F Grade F (ATC)

F Grade F Chemical Properties. For example Heat analysis C 0. 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: E Type 3 bolts conforming to Table 2, or Type 3 bolts which have a copper minimum Heat Analysis of 0. C Bolt pitch oversize limit in case of dispute. Material within the plain gauge limits which meets the coating thickness requirements and assembles freely need not be measured to this tolerance.


D Hot-Dip galvanized is typically tapped after coating. F280 coatings are typically applied after nut tapping. E Grade 5 of this coating meets the supplementary lubrication requirements of A S1.

F Grade 1 of asrm coating meets the supplementary lubrication requirements of A S1. Performance requirements shall be specified by the purchaser and agreed to in writing.

The table above is inspired by Table A1. Proof Load C Min.

Proof Load D Min. C Proof load length measurement.

ASTM F3125

N Bearing type connection with threads included in the shear plane. X Bearing-type connection with threads excluded from the shear 2f280. When astj, the same requirements of A and this specification, and Annex A1, including overtap, coating, rotational capacity and proof load testing apply.

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. Kegs and skids weight is an approximation.
