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.

Brass cup point socket set screws are headless threaded fasteners used to secure collars, hubs, gears, pulleys, knobs, handles, and other components to shafts or mating parts. The internal hex socket allows installation through compact openings, while the cup-shaped point creates localized rim contact against the mating surface.
Cup point geometry is commonly selected where concentrated holding contact is needed to help resist relative movement between assembled components. Depending on the mating material and installation conditions, the point may leave a witness mark or shallow indentation on the contacted surface. These fasteners are often used in electrical equipment, instrumentation, controls, enclosures, fixtures, light-duty machinery, adjustment assemblies, maintenance repairs, and replacement applications where brass is specified.
Brass provides a nonferrous material option with a distinctive appearance, general resistance to ordinary atmospheric corrosion, and useful electrical conductivity. Final product selection should reflect the actual mechanical load, environmental exposure, electrical requirements, mating material, and dimensional needs of the assembly.
Cold Headers supplies brass cup point socket set screws in a range of inch thread sizes and lengths, including uncommon and difficult-to-source configurations. Individual product pages provide exact thread size, screw length, nominal diameter, hex socket size, cup point diameter, and other verified technical information where available.
Begin by confirming the required thread size and screw length. Then review the hex socket size to ensure the proper installation tool is available. Cup point diameter, mating-surface material, available access, required holding action, allowable surface marking, and whether brass is appropriate for the load and service conditions should also be considered. Cup point set screws should not be substituted automatically for flat, oval, cone, or dog point styles because each point geometry creates a different contact condition.
Cold Headers Inc. has supplied specialty industrial socket fasteners since 1962. Our catalog is organized to help engineers, distributors, maintenance teams, and purchasing professionals locate exact sizes, uncommon lengths, and hard-to-find brass socket set screws without unsupported inventory claims.

Brass flat head socket cap screws are designed for countersunk assemblies where the installed head should sit flush with, or close to, the surrounding surface. Their flat-head geometry reduces surface projection, while the internal hex socket allows installation with a hex key in areas where external wrench clearance may be limited.
These fasteners are commonly used in electrical equipment, decorative hardware, instrumentation, controls, access panels, light-duty machinery, fixtures, display equipment, enclosures, and maintenance applications where brass material and a countersunk profile are specified. A properly prepared countersink helps the head seat cleanly and can reduce snag points, improve clearance around adjacent parts, and create a smoother finished surface.
Brass is often selected for its appearance, general corrosion resistance, electrical conductivity, and nonferrous composition. It can be useful in assemblies where alloy steel or stainless steel is not the specified material. Final product selection should still reflect the actual mechanical, environmental, electrical, and dimensional requirements of the application.
Cold Headers supplies brass flat head socket cap screws in a range of inch thread sizes and lengths, including uncommon and difficult-to-source configurations. Individual product pages should be reviewed for exact thread size, overall length, nominal body diameter, head diameter, hex socket size, key engagement where verified, and other available dimensional information.
Begin by confirming the required thread size and overall screw length. Then review the head diameter and countersink requirements to make sure the fastener seats properly without excessive projection or over-travel. The hex socket size should match the intended installation tool, while the available body and key-engagement dimensions can help confirm fit and drive access. Do not assume a brass fastener is interchangeable with a steel or stainless product solely because the nominal size is the same.

Brass button head socket cap screws feature a smooth, low-profile rounded head with an internal hex drive, making them well suited for applications requiring a compact fastening solution together with the appearance and corrosion resistance of brass. The broad bearing surface of the button head helps distribute clamping force while maintaining a lower profile than a standard socket head cap screw.
Manufactured from brass, these fasteners are commonly selected for electrical equipment, instrumentation, decorative hardware, laboratory equipment, architectural assemblies, pumps, valves, electronic equipment, maintenance repairs, and OEM applications where brass is the specified material. The internal hex drive allows installation where external wrench clearance is limited while providing a clean, finished appearance.
Proper fastener selection should consider thread size, screw length, nominal body diameter, head diameter, head height, hex socket size, mating-thread engagement, installation access, and service environment. Individual product pages provide verified engineering dimensions to help engineers and purchasing professionals specify the correct fastener for demanding industrial and commercial applications.
Cold Headers supplies brass button head socket cap screws in a broad range of inch thread sizes and lengths, including standard, uncommon, and difficult-to-source configurations. Our catalog is organized to simplify exact-size sourcing while providing consistent engineering information across every product family.
Begin by confirming the required thread size and screw length. Review the nominal body diameter, head diameter, head height, hex socket size, installation clearance, mating-thread engagement, and operating environment before selecting a fastener. Final material selection should reflect the mechanical, environmental, and appearance requirements of the completed assembly. 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.
