ASTM A193 B7 Threaded Rod

Wed, 23 Aug 2023 12:42:45 +0000

B7 threaded rod is the alloy-steel stock we use to manufacture our B7 studs. We hold it in Umm Al Quwain in 3 m and 10 ft lengths from ¼" to 4" and cut it into studs of any length in-house, so short runs, odd lengths and urgent flange bolt lists are turned around quickly.

ASTM A193 B7 Threaded Rod explained

ASTM A193 B7 threaded rod is quenched-and-tempered chromium-molybdenum alloy steel (AISI 4140) with a minimum tensile strength of 125 ksi, threaded along its full length. It is produced to ASME B18.31.3 with coarse (UNC), 8-pitch (8UN) or metric threads and is the base material for stud bolts in high-temperature, high-pressure piping.

Applications

Stud bolt production for ASME flanges
Anchor rods for equipment and vessel skirts
Tie rods on expansion joints and spring hangers
Heat exchanger and boiler bolting
High-strength hangers and brackets
Site-cut studs for turnaround and maintenance

Standards, grades & finishes

Rod conforms to ASTM A193 / A193M Grade B7 (B7M and B16 on request), dimensions to ASME B18.31.3 / B18.31.4M, threads UNC / 8UN Class 2A to ASME B1.1 or metric 6g. Supplied plain (oiled), hot-dip galvanized, zinc plated or PTFE / Xylan coated. A194 2H nuts and F436 washers supplied to match. Mill test certificate with chemical and mechanical results per heat.

Anchor bolts, studs and plate washers are manufactured in our own ISO 9001:2015 plant in Emirates Modern Industrial Area, Umm Al Quwain, with calibrated in-house dimensional and thread inspection. Tensile, hardness and chemical testing is carried out by independent UAE-accredited laboratories, and EN 10204 3.1 certificates are issued with every batch. We supply across the GCC, MENA and Africa.

DIN 975 threaded rod is the raw stock our studs are cut from, and we hold it in Umm Al Quwain in 1 m and 3 m lengths from M6 to M52 — carbon steel 4.6, 8.8 and 10.9, stainless A2 and A4, plain, zinc plated or hot-dip galvanized. We cut, chamfer and supply studs to any length from it in-house.

Threaded Rod DIN 975 explained

Threaded rod (all-thread, threaded bar) is a straight bar threaded along its entire length. DIN 975 covers the rod itself and DIN 976 the studs cut from it. It is the universal material for hangers, anchors, tie rods and site-made studs: cut to length, add nuts and washers, and it becomes a fastener for almost any application.

Applications

Pipe and duct hangers, HVAC supports
Cable tray, ceiling and fire-fighting brackets
Chemical anchor and resin anchor rods
Formwork tie rods and scaffolding
Site-cut studs and extension rods
Electrical, solar and telecom mounting

Standards, grades & finishes

Rod to DIN 975 / DIN 976-1, thread ISO 965 6g metric coarse (fine on request), property class 4.6, 5.8, 8.8, 10.9 to ISO 898-1, stainless A2-70 and A4-80 to ISO 3506. Also available in UNC to ASME B1.1. Finish self colour, electro zinc plated (blue / yellow), hot-dip galvanized to ISO 1461. Supplied with mill certificates.
