ASTM F1852 PDFJune 21, 2020
The ASTM F Grade F, (Also known as A TC bolts) specification cover heat treated, steel, tension control bolt-nut-washer assemblies, also referred. ASTM F Standard Specification for “Twist Off” Type Tension Control Structural Bolt/Nut/Washer Assemblies, Steel, Heat Treated, / ksi Minimum. Question, Whats the difference between F and F? I have each ASTM spec in front of me. F is TC assemblies heat treated w/

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.
ASTM F Grade F (ATC)
D Other distinguishing markings for type 3 are permitted at the manufacturers option. F Grade F Chemical Properties. For example Heat analysis C 0.
D Steel, as defined by the American Iron and Steel Institute, shall ast 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 astk coating thickness requirements and assembles freely need not be measured to this tolerance. D Hot-Dip galvanized is typically tapped after coating.
Others 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 this 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.

B Previous versions of A and F required tensile testing based on ksi min. C Proof load length measurement.
Aatm Bearing type connection with threads included in the shear plane. X Bearing-type connection with threads excluded from the shear plane. When coated, the same requirements of A and this specification, and Annex A1, including overtap, coating, rotational capacity and proof astj 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. The real weight may slightly differ from what is shown here.
