Mining & Minerals fasteners & bolting.
Heavy hex bolting, U-bolts and wear parts built to survive abrasion, shock and weather.
Crushers, mills, and conveyors shake fasteners loose and wear them out. High-strength alloy bolting, 12-point heads for confined torque, and abrasion-tolerant custom machined components built for the maintenance cycle.

Grades mining & minerals runs on.
ASTM F3125 Grade A325 Structural Bolts (120 ksi)
The structural steel connection bolt: heavy hex head, 120 ksi tensile, ½ to 1½ in., quenched and tempered, with the twist-off F1852 and metric A325M variants in the same specification.
ASTM F3125/F3125M Grade A490 · Type 1 and Type 3ASTM F3125 Grade A490 Structural Bolts (150 ksi)
The high-strength structural bolt: alloy steel, 150 to 173 ksi tensile, ½ to 1½ in., never hot-dip galvanized — with the twist-off F2280 and metric A490M variants in the same specification.
ASTM A354 Grade BD · SAE J429 Grade 8SAE Grade 8 / ASTM A354 Grade BD Bolts (150 ksi)
The high-strength alloy bolt: quenched and tempered alloy steel at 150 ksi tensile and 130 ksi yield in all sizes to 4 in. — Grade 8 in SAE terms, A354 BD in ASTM terms.
ASTM A322 bar · ASTM A434 Q&T barAISI 4140 Alloy Steel (UNS G41400)
The workhorse Cr-Mo steel behind B7, L7 and Grade 7 — the bar stock for studs, shafts, couplings and any part that needs 100 to 150 ksi and good toughness.
ASTM A322 bar · ASTM A434 Q&T barAISI 4340 Alloy Steel (UNS G43400)
The deep-hardening high-strength steel — 4340 reaches 155 ksi and beyond in large sections — for crankshafts, drilling tools, aircraft parts and A320 L43 bolting.
