Steel Hex Bolt

ASTM F3125/F3125M is a structural bolt specification covering inch and metric bolt grades. This specification contains 4 inch series bolting grades: A325, F1852, A490, and F2280. These will be addressed in this article. When looking at the mechanical requirements of bolts it appears that a grade A325 and SAE J429 Grade 5 are identical as do the grade A490 and the SAE J429 Grade 8. This begs the question, "Can an SAE J429 Grade 5 be used when an ASTM F3125 grade A325 is

Hex bolts (six sided heads) are the industry standard for fasteners with forged heads. ASTM A307 grade A bolts, all SAE hex bolts, and several other common specifications require a standard (finished) hex head. For specifications such as A307 grade B, A325 and A490 that require a heavy hex pattern, refer to dimensional tolerances for heavy hex bolts or structural bolts. .

This specification covers two types of quenched and tempered, steel, metric heavy hex structural bolts having a minimum tensile strength of 830 MPa (Note 1). Formerly under the jurisdiction of Committee F16 on Fasteners, this specification was withdrawn in May 2016 and replaced by Specification F3125/F3125M for High Strength Structural Bolts, Steel and Alloy Steel, Heat Treated, 120 ksi (830 MPa) and 150 ksi (1040 MPa) Minimum Tensile Strength, Inch and Metric Dimensions.

Specification DIN 960 Hex Head Bolts are partially threaded bolts with fine and extra fine external machine screw threads (the space between fine and extra fine threads is less than coarse, wider-spaced threads). Mated with internally threaded holes and nuts, they are similar to ISO 8765 except for some dimensional differences. Available in Class 8.8 and 10.9 steel, zinc plating inhibits the formation of rust while plain finish does not have any corrosion protection. Thread

Specification The hex head cap screw is a common fastener in construction and machine assembly. The screw head is designed to fit a ratchet or spanner torque wrenches allowing you to tighten the screw to your exact specifications. Hex head cap screws are typically used to create a bolted joint, in which a threaded shaft exactly fits a corresponding tapped hole or nut. CL4.8 screws tend to be used in construction for joining wood components. CL8.8 screws are used in small

ANSI ASME B18.2.1 Carbon Steel Heavy Hex Cap Screw Manufacturing QBH Bolt manufactures heavy hex bolts from 3/8″ diameter through 3″ diameter in most ASTM, AASHTO, and SAE specifications. Special tooling can be created to produce nonstandard head dimensions or bolt heads with your company’s name and/or logo. Several ASTM specifications require a hex head that is larger than a standard (finished) hex head. These specifications include: A193, A320 and A307B. Although A325 and

JIS B1180 Hexagon Head CL4.8 5.8 6.8 Carbon Steel Bolt Specification JIS B1180 Small Head Hex Bolts have the smallest width heads of all metric hex bolts/hex head cap screws. The width across flats (wrench size) of the three available sizes is 1 to 3 mm smaller than equal sized DIN 931, ISO 4014 and ANSI B18.2.3.1M bolts, while their head height is slightly larger. Otherwise, like their counterparts, they are partially threaded (PT) or fully threaded (FT) with external
