Value Collection KP44014 1/4-20 X 4 in Grade 8 Hex Cap Screw

Product Description

The VALUE COLLECTION KP44014 is a Grade 8 steel hex head cap screw sized 1/4-20 x 4 inches, supplied in a 50-piece pack. Manufactured to ASTM A354 BD standards, it delivers high tensile strength suitable for demanding fastening applications in mechanical, structural, and industrial assemblies. The zinc-plated finish provides baseline corrosion resistance for general-purpose use. Thread standard is UNC (Unified National Coarse) with partial threading along the shank. Length measurement is taken under the head. Licensed tradespeople and maintenance technicians working in HVAC equipment assembly, plumbing fixture mounting, electrical enclosure fabrication, and general mechanical work will find this fastener a reliable shelf stock item.

This screw is appropriate for use in light structural connections, equipment mounting, and general mechanical fastening where a high-strength, inch-system UNC fastener is required. The 4-inch length under head accommodates thicker material stackups, spacers, or standoff applications. The partial thread design allows for clamping without thread engagement across the full grip length, which is common in bolted joint applications where shank bearing load is preferred. Sold in packs of 50, this SKU is suited for shop stock, service vans, and production-line use.

Key Features

• Grade 8 steel construction meets ASTM A354 BD for high tensile and proof load strength
• 1/4-20 UNC thread for broad tooling and nut compatibility
• 4-inch length under head suits thicker material assemblies and standoff configurations
• Partial threading preserves shank bearing surface for clamping applications
• Zinc-plated finish provides general corrosion protection in dry and low-humidity environments
• 50-piece pack quantity supports shop stock and repeat-use scenarios

Compatibility

Designed as a standard inch-system UNC hex head cap screw for use with 1/4-20 threaded nuts, inserts, and tapped holes in steel, aluminum, and other machinable substrates across mechanical and structural applications.

Installation Notes

Installation is performed by mechanics, millwrights, HVAC technicians, plumbers, and electricians using standard hex wrenches or socket drivers. De-energize and lock out equipment before fastening work on any live mechanical or electrical assembly per applicable OSHA lockout/tagout procedures. Use a calibrated torque wrench when torque specifications are called out by the equipment manufacturer. Do not exceed the rated proof load for this fastener grade when determining final clamp load.
