Button Head Socket Cap Screws
Why Choose Button Head Socket Cap Screws?
Our button head socket cap screws at AlbanyCountyFasteners.com are designed for precision fastening in metal-to-metal applications where a smooth, finished look is essential. Made from high-strength alloy steel, these button head socket screws feature a low-profile, rounded head and an internal hex drive for high-torque installation. Their fine or coarse threads ensure a secure hold in pre-tapped holes or with nuts. Available in imperial sizes like #10-24, 1/4"-20, and 3/8"-16 with lengths from 1/4" to 2", they’re ideal for applications requiring both strength and aesthetics.
- Low-Profile Design: Rounded head for a smooth, finished appearance.
- High Strength: Alloy steel for durable performance.
- Internal Hex Drive: Allows high-torque installation with an Allen wrench.
- Versatile Threading: Fine or coarse threads for secure fastening.
Applications for Button Head Socket Cap Screws
Button head socket screws are tailored for projects requiring strong, aesthetically pleasing fasteners. Their design makes them suitable for:
- Machinery and equipment assembly
- Automotive and aerospace components
- Electronics and panel installations
- Furniture and decorative metalwork
Frequently Asked Questions (FAQ)
Button head socket cap screws are high-strength alloy steel fasteners with a low-profile, rounded head and an internal hex drive. They feature fine or coarse threads, designed for secure metal-to-metal fastening in pre-tapped holes or with nuts.
Are button head socket cap screws suitable for outdoor projects?These alloy steel screws lack corrosion resistance and are best for indoor or non-corrosive environments. For outdoor or corrosive settings, consider stainless steel screws for enhanced durability.
How do I choose the right size button head socket cap screw?Select based on thread size, length, and load requirements. Common sizes include #10-24, 1/4"-20, and 3/8"-16, with lengths from 1/4" to 2". Check sizing charts or consult our team for guidance.
Button Head Socket Cap Screws FAQs<
See the accordion below for quick answers on measuring length, head clearance, material choice, and torque guidance for button heads.
A low, rounded head with an internal hex drive; wider head OD spreads load and offers a finished look.
From under the head to the tip (flat heads are measured overall; button/standard measure under head).
When you want lower profile and broader bearing on thin/soft materials, and ultra-high torque capacity isn’t required.
Alloy steel black oxide for high strength indoors; 18-8/304 for general corrosion resistance; 316 for marine/coastal or chemical exposure.
Often not, the wider head provides added bearing. Use washers or flanged components if surfaces are delicate or loads are high.
Follow size/material torque guidance. Button heads have shallower recesses than standard socket heads, avoid over-torque and recess rounding.
Yes, ensure adequate bearing area (washer/flange if needed) and avoid over-tightening to prevent crushing or creep.
