Unifit Metalloys Inc is a Manufacuring,Supplier & Exporter of ASTM A320 L7 Stud Bolts This is the most common A320 bolt grade. A320 Grade L7 bolts and threaded studs are manufactured from alloy steel with chromium, manganese, and molybdenum. The bolts undergo a heat treating process to reach their required mechanical properties. L7 threaded studs and short, headed bolts are readily available in the marketplace. These bolts are typically bought and sold in a plain, bare metal finish. L7 bolts are available through 4” in diameter. A320 Grade L7 bolts larger than 1/2″ diameter require a Charpy impact test.
A320 Grade L7 is intended for low-temperature service down to -150° F and has a minimum Charpy impact value of 20-ft-lbf at this temperature.
Unifit Metalloys Inc. stocks ASTM A320 Stud Bolts from 3/8” - 4” diameter in Imperial Sizes: Plain (black) finish, Teflon Blue, and Cadium Plating. We also stocks B8 and B8M stud bolts. We can also provide larger stud bolts, stud bolts made from different materials (L7, L43, B8M, B8M, , Alloy 20, Monel, Hastelloy, Inconel, Titanium, etc), as well as different coatings.

ASTM A193 specification covers alloy and stainless steel bolting for pressure vessels, valves, flanges, and fittings for high temperature or high pressure service, or other special purpose applications. Several grades are covered, including ferritic steels and austenitic stainless steels designated B5, B6, B7, B8, B8M, etc. Selection will depend upon design, service conditions, mechanical properties, and high temperature characteristics. This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable A193M specification designation (SI units), the inch-pound units shall apply
