ASTM A193 Grade B7 Full Thread Hex Bolts


ASTM A193 Grade B7 Full Thread Hex Bolts

 

ASTM A193 Gr. B7 Bolts and Threaded studs are manufactured from a Chromium Molybdenum Steel and are Quenched and Tempered (heat treated) to develop the desired mechanical properties (strength). Grade B7 is the most common grade of A193 bolts used in construction. B7 threaded studs and short, headed bolts are readily available in the marketplace. Grade B7 bolts are commonly used in pipe flange connections. These bolts are typically bought and sold in a plain, bare metal finish but are often hot-dip galvanized, zinc plated, Xylan coated, PTFE coated, or otherwise coated for corrosion resistance.

A193 Grade B7 Class Bolts are manufactured from AISI 4140/4142 low Carbon Alloy Steel Grades followed by Quenching & Tempering. We manufacture these Bolts with great precision & Quality. These grade bolts are also denoted as Grade 7 Bolts, B7 Bolts etc. We also offer B7 Studs/B7 threaded bars/B7 Threaded rods.

Presinox Impex is Largest Stockist & Supplier of these Bolt Fasteners in various sizes & Coatings.

ASTM A320 Grade L7 Bolts, studs, and other fasteners under the L7 grade have the same chemical and physical properties as B7. Additional requirement that it meet a Charpy Test at 150 degrees F is needed. Such fasteners are commonly used for low temperature service.
