Value Collection 019143P Low Head Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 019143P is a low head socket cap screw designed for applications where a standard cap screw head height would interfere with mating components or adjacent hardware. Sized at 1/4-20 UNC with a 3/8-inch length under head, this fastener is fully threaded and driven with a 1/8-inch hex key. It is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and reduces light reflection in finished assemblies. The low-profile head geometry makes it well suited for tight-clearance installations in mechanical, industrial, and OEM equipment applications. Machinists, millwrights, and assembly technicians are the primary installers of this fastener type.

This screw is used in applications where head clearance is restricted and a standard socket cap head cannot seat flush or clear surrounding structure. Common use cases include panel assemblies, jigs, fixtures, tooling plates, and precision mechanical subassemblies. The coarse UNC thread pitch is standard for general-purpose inch-system fastening. The black oxide finish is appropriate for indoor or protected environments where light surface treatment is acceptable. This fastener conforms to ASME/ANSI B18.8 standards, making it a specification-grade choice for controlled assembly work.

Key Features

• Low socket cap head profile reduces clearance requirements compared to standard socket cap screws
• Fully threaded 1/4-20 UNC coarse thread for consistent engagement across the full shank length
• 1/8-inch hex socket drive for use with standard hex keys or hex drivers
• Alloy steel construction provides strength appropriate for industrial fastening applications
• Black oxide finish offers light corrosion resistance and a matte appearance
• Conforms to ASME/ANSI B18.8 fastener standard

Compatibility

Designed as a specification-grade low head socket cap screw per ASME/ANSI B18.8 for use in inch-system assemblies requiring a 1/4-20 UNC coarse thread fastener with a reduced-height head profile.

Installation Notes

Installation should be performed by qualified mechanical assemblers or machinists using a properly sized 1/8-inch hex key or hex bit driver. Verify thread engagement depth and confirm the mating material is compatible with alloy steel fasteners before assembly. Black oxide finish does not provide heavy corrosion protection; avoid use in wet or outdoor environments without additional sealing or coating. Follow applicable torque guidelines for 1/4-20 alloy steel fasteners per your assembly specification or engineering documentation.
