Value Collection 93052 Button Socket Cap Screw 4-40 3/8 in

Product Description

The VALUE COLLECTION 93052 is a 4-40 button socket cap screw designed for low-profile fastening applications where a rounded head profile is required. Manufactured from 18-8 stainless steel with a bright, uncoated finish, this screw provides corrosion resistance suitable for general industrial, mechanical, and light-duty structural assemblies. The hex socket drive accepts a 1/16-inch hex key for installation in confined spaces where a standard driver cannot reach. Thread length under the head measures 3/8 inches, and the thread fit class is 3A per ANSI/ASME B18.3 and ASTM F837 standards. Sold in a package of 50 pieces.

This fastener is suited for residential and commercial applications requiring a compact, corrosion-resistant screw in light-gauge assemblies, electronics enclosures, instrumentation panels, and precision mechanical components. The 4-40 UNC thread size is common in small-device fabrication, HVAC control board mounting, and equipment chassis assembly where clearance around the fastener head is limited. Licensed tradespeople and fabricators working to ANSI specifications will find this screw a direct fit for standard 4-40 tapped holes.

Key Features

• 18-8 stainless steel construction for corrosion resistance in damp or mildly corrosive environments
• Button head profile reduces protrusion and provides a smooth, low-profile seating surface
• 1/16-inch hex socket drive allows installation in tight, recessed, or confined locations
• 3A thread fit class meets ANSI/ASME B18.3 and ASTM F837 fastener standards
• Right-hand UNC thread for compatibility with standard 4-40 tapped holes
• Bright, uncoated finish maintains dimensional tolerances without coating buildup

Compatibility

Designed as an OEM-style replacement or stock fastener for any assembly requiring a 4-40 UNC button socket cap screw with a 3/8-inch length under head.

Installation Notes

Installation should be performed by a qualified technician or fabricator using a 1/16-inch hex key or ball-end driver. De-energize and lock out any electrical equipment before installing fasteners in or near live assemblies. Do not overtighten into tapped holes in soft materials such as aluminum or plastic, as the 4-40 thread is fine and susceptible to stripping. Follow applicable ANSI torque guidelines for the base material and thread size.
