Value Collection 201113PR Button Socket Cap Screw 1/4-28

Product Description

The VALUE COLLECTION 201113PR is a button socket cap screw designed for applications requiring a low-profile head with a secure hex socket drive. This 1/4-28 UNF fully threaded fastener measures 1 inch in length under the head and uses a 5/32 inch hex key for installation. Manufactured from alloy steel with a black oxide coating, it delivers hardness in the 36-43 HRC range and corrosion resistance suited to general industrial and mechanical assembly work. Licensed trades and maintenance professionals use this fastener where a standard hex cap would protrude too far or interfere with adjacent components.

This button socket cap screw is used in light machinery, tooling fixtures, enclosures, and equipment panels where a flush or near-flush head profile is required. The 1/4-28 UNF thread standard makes it appropriate for fine-thread applications that demand tighter thread engagement, including vibration-prone assemblies in HVAC equipment, electrical enclosures, and mechanical subframes. It is sold individually per order line but subject to a minimum order quantity of 100 pieces.

Key Features

• Button head profile provides low clearance over the fastened surface
• 5/32 inch hex socket drive for standard hex key or socket bit installation
• 1/4-28 UNF fully threaded with right-hand thread direction and Class 3A thread fit
• Alloy steel construction with 36-43 HRC hardness range
• Black oxide finish for mild corrosion resistance and reduced light reflection
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 1/4-28 UNF button socket cap screw per ANSI/ASME B18.3 and ASTM F835, fitting any tapped hole or threaded insert conforming to that specification.

Installation Notes

Install with a 5/32 inch hex key or matching socket bit. Verify the receiving thread is clean and free of debris before driving. Do not exceed the rated torque range for a 1/4-28 Class 3A alloy steel fastener as specified in your application's engineering documentation. Black oxide coating provides only mild corrosion protection — apply a thread lubricant or sealant if the installation environment involves moisture or chemicals.
