strength requirements by grade portland bolt
ASTM A325 covers high strength structural bolts used in structural steel connections. A325s have a heavy hex head, a full body diameter, and are normally short in overall length since they are connecting steel to steel. Unlike other ASTM grades, A325 is specific not only in the chemical and mechanical requirements, but also in the allowed
These bolts are liquid quenched between a range of 50 °F to 900 °F and they can be air quenched at temperatures ranging between - 40 °F to 900 °F. The minimum yield and tensile strength requirements for the ASTM A193 Grade B7m Bolts are reduced as opposed to the B7 grade bolt. ASTM A307 Grade A Specification - Boltport FastenersASTM A307 Grade A specification for carbon steel bolts, studs, threaded rods and other externally threaded fasteners with minimum tensile strength requirement of 60 ksi. ASTM A307 specifications covers requirements for chemical composition, mechanical properties, heat-treatment, recommended nuts-washers and bolt markings for Grade A Bolts.
The three grades 36, 55, and 105 designate the minimum yield strength (ksi) of the anchor bolt. The bolts can be either cut or roll threaded and a weldable grade 55 can be substituted for grade 36 at the suppliers option. Color coding on the end 36 blue, 55 yellow, and 105 red helps facilitate easy identification in the field. ASTM Fastener Standards Specifications For A307 Bolts & Jul 01, 2015 · The fasteners are designated by Grade denoting tensile strength and intended use, as follows:Grade A:Bolts and studs having a minimum tensile strength of 60 ksi and intended for general applications. Grade B:Bolts and studs having a tensile strength of 60 to 100 ksi and intended for flanged joints in piping systems with cast iron flanges. Grade C:Replaced by Specification F1554 Gr.36
Jul 01, 2015 · This specification covers the chemical and mechanical requirements of three grades of carbon steel bolts and studs in sizes 14 in. through 4 in. ASTM A307 is the most common of all bolt specifications and is often manufactured using A36 round bar. The fasteners are designated by Grade denoting tensile strength and intended use, as  ASTM-A193 Mechanical Properties - Lightning Bolt & Supply The term bolting used in this specification includes bars, bolts, hex bolts, hex head cap screws, screws, studs, stud bolts, and wires. Although A193 fastener grades are available in UNC (unified national course) and UNF (unified fine) thread pitch, it is common to find sizes 1 and larger in 8 thread (8 TPI threads per inch).

This is the highest strength version of the F1554 specification, with a minimum yield strength of 105 ksi, covering anchor bolts in diameters ranging from 1/2 through 3. F1554 Grade 105 - F1554 Anchor BoltsThis is the highest strength version of the F1554 specification, with a minimum yield strength of 105 ksi, covering anchor bolts in diameters ranging from 1/2 through 3. Galvanizing. F1554 grade 105 bolts can be galvanized even though they are relatively high in strength.
S3:Instead of the standard color coding of yellow spray paint to indicate Grade 55, supplemental requirement S3 can be specified by the purchaser to have a permanent grade identification on the end of the anchor bolt that projects from the concrete. S4:The purchaser may also specify that Grade 55 be Charpy impact tested at +40F (+5C). The minimum Charpy V-notch energy requirement is an FAQs Archives - ASTM A193Unlike most other ASTM specifications covering construction fasteners, the A193 specification requires 8 threads per inch for bolts larger than 1 diameter. The 8 Unified National thread series (8UN) provides increased tensile and shear strength due to a larger tensile stress area and minor diameter and 8 pitch threads reduce the probability of nuts backing off due to vibration.
Grade B16. ASTM A193 Grade B16 bolts and threaded studs are manufactured from a chromium-molybdenum-vanadium alloy steel. Although A193 Grade B16 bolts and studs have similar strength requirements as Grade B7, the vanadium and higher tempering temperature helps the fasteners retain their molecular structure and strength under higher ambient temperatures than Grade B7. Hex Coupling Nuts - Portland BoltA194; A563; F594; Hex couplers are used to connect two pieces of threaded material. Hex and heavy hex couplers are threaded right hand. If a right hand-left hand coupler is needed, consider using a sleeve nut.. See our nut compatibility chart to determine the compatible hex coupler for a specific grade of bolt. Since hot-dip galvanizing typically adds 2.2 to 5 mils of thickness to the threaded

Heat Treating Once threaded, the bolts need to be heat treated. This is the same two part process (quench and temper) required for cold forged structural bolts. They are put into large ovens in a controlled environment and introduced to regulated temperatures for an amount of time deemed necessary to get the bolt strength into the parameters required by the ASTM A325 specification.

This works when analyzing what grade of material should be used for a given application, but this doesnt tell us the actual or ultimate strength of that material for a specific diameter.
Portland Bolt manufactures custom round bend U-bolts from 1/2 through 4 in diameter to virtually any ASTM specification. They are provided either plain finish or hot-dip galvanized. Other metals like 304 and 316 stainless steel U-Bolts are also manufactured. All operations, including the galvanizing process, are performed in-house. Cutting Specifications - Headed Anchor BoltsAlthough engineers often specify A193 Grade B7 for anchor bolt applications, ASTM F1554 Grade 105 may be a more appropriate specification since it possesses virtually identical chemical and mechanical (strength) requirements. Portland Bolt is able to manufacture headed anchor bolts meeting the requirements of ASTM A193 Grades B8 and B8M, both of which are stainless steel.

Therefore, high strength cements came into picture through IS-8112, OPC 43 and IS- 12269, OPC- 53 grade to take care of these specific requirements. All the three grades viz. IS 269 (33-grade), IS 8112 (43 -grade) and IS 12269 (53 -grade) were ordinary Portland cements. Technical Info and ASTM Specifications - Galvanized Anchor The most common grades used for anchor bolts are the high strength alloy steel grade L7 and the stainless steel grades B8 and B8M.

For those reasons, any grade 2 bolt above ¾ diameter, and any diameter of grade 2 bolt longer than 6 are governed by the mechanical requirements of J429 grade 1, which is also very similar to ASTM A307A. As for grade 5 fasteners, the reasoning is similar.
