High-Strength Carbon Steel Heavy Hex Cap Screws

The requested product, while incorrectly named as "A194 2H Screws," points toward a need for a high-strength, heat-treated carbon steel threaded fastener designed for high-load applications. Our Heavy Hex Cap Screws are manufactured from an Alloy Steel (similar to AISI 4140) and are quenched and tempered to achieve mechanical properties comparable to ASTM A193 Grade B7 (the stud bolt commonly mated with A194 2H nuts). These screws are used when the fastener threads directly into a tapped hole on a machine part or vessel wall, requiring high tensile strength to maintain clamping force. The Heavy Hex Head provides the necessary bearing area and wrenching surface for high-torque installation. Zeron Fasteners manufactures these cap screws to exacting dimensional standards, ensuring reliable performance in demanding machinery and tooling where high strength and structural integrity are essential.
