Brass Socket Head Cap Screws

Nobody specifies a brass socket head cap screw for brute clamping force — that's what our alloy steel line is for. A Brass Socket Head Cap Screw gets picked for what the metal itself does: it conducts electricity, it ignores magnets, it shrugs off water service, and it looks finished on the day it's installed and ten years later. The socket head format adds its own advantages to that list — a compact cylindrical head that seats flush in a counterbore, and an internal hex drive that wrenches in tight quarters where an open-end wrench can't swing. That combination is why these screws show up in electrical equipment, grounding and panel work, instrumentation, laboratory devices, plumbing and fluid-handling equipment, and architectural hardware where the fastener stays visible.

One piece of shop wisdom that belongs on this page: brass asks for a lighter hand. It's a softer metal than steel, which is part of its charm — but it means the correct-size hex key, fully seated, and torque appropriate to brass rather than the number you'd use on an alloy screw. Treated that way, the socket stays crisp through repeated service. Treated like steel, it won't.

Brass alloys vary in composition and corrosion behavior. If your application involves continuous moisture, chemicals, or elevated temperatures, contact our sales team to confirm the right alloy for your service conditions. For saltwater and marine environments, we recommend our 316 Stainless Steel fasteners.

Our online catalog highlights our standard inventory but does not represent every size or configuration we can supply. Brass socket products are a thin-stock item across the industry — which is exactly why we keep them — and we can frequently quote:

• Special lengths
• Non-catalog sizes
• Difficult-to-source brass fasteners
• OEM production quantities
• Distributor volume requirements
