Alloy Steel Fasteners

Alloy Steel Fasteners

Boltport Fasteners is a reputed name among High Tensile Alloy Steel Fasteners manufacturers and suppliers. Alloy steel Boltport offers complete range of alloy steel bolts, screws, stud bolts, threaded rods, nuts and washers. Alloy steel grades 4130, 4140, 4340 and 8620 (20MnCr5) are commonly used material for producing these high strength alloy steel fasteners.

Alloy steel fasteners are supplied in quenched and tempered condition with charpy impact testing and are primarily used for low temperature bolting applications. ASTM A193 Grade B7, B7M, A320 L7, L7M, L43, ISO 898-1 Grade 8.8, 10.9 & 12.9 are among frequently manufactured alloy steel bolt grades.
