A Unless otherwise specified on the inquiry and order, the choice of an alloy from within a group shall be at the discretion of the fastener manufacturer B See section 4.
ASTM F Specification – Boltport Fasteners LLP
D When approved by the purchaser, alloysSe, or XM1 may be furnished. E When approved by the purchaser, alloy F may be furnished. F When approved by the purchaser, alloys or Se may be furnished. A – Machined from annealed or solution annealed stock thus retaining the properties of the original material; or hot formed and solution annealed.
AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age hardened after forming. CW – Headed and rolled from annealed stock thus acquiring a asmt of cold work.
ASTM F – Portland Bolt
SH – Machined from strain hardened stock or cold worked to develop the specific properties. Condition CW – When Condition CW is specified, the austenitic alloys shall be annealed in accordance with Condition A, generally by the raw material manufacturer and thenc old worked to develop the specified properties.
Condition AF – When Condition AF is specified, the austenitic alloys shall be annealed in accordance to Condition A after all cold working including heading and threading has been completed.
A Minimum values except where shown as maximum or as a range. B legend of conditions: AF – Headed and rolled from annealed stock and then reannealed AH – Solution annealed and age w593 after forming CW – Headed and rolled from annealed stock thus acquiring a degree of cold work.
C The yield and tensile strength values for full size products shall be computed by dividing the yield and maximum tensile load value by the stress area for the product size and thread sizes determined in accordance with Test Methods F D Yield strength is the stress at which an offset of 0. A Where options are given, all the tests under an option shall be performed.
Option A tests should be made whenever feasible.
B Tests that are not mandatory C Special fasteners are those fasteners with special configurations including drilled heads, reduced body, etc. Special fasteners have full size heads a53 be tested as specified for stud bolts and other bolts. A Tensile stress areas are computed using the following formula: Hex head, square head and hex socket cap screws.
