Value Collection KP44079 Hex Cap Screw 1/2-13 X 1-3/4 in Grade 8

Product Description

The VALUE COLLECTION KP44079 is a Grade 8 steel hex head cap screw designed for high-strength fastening applications. Sized at 1/2-13 thread with a 1-3/4 inch length under head, this fully threaded fastener meets UNC thread standards and complies with ASTM A354 BD specifications. The zinc-plated finish provides a baseline level of corrosion resistance suitable for general indoor and light outdoor use. Each package contains 50 screws. This fastener is used by mechanics, millwrights, electricians, pipefitters, and general tradespeople wherever a high-tensile hex cap screw is required.

Grade 8 hex head cap screws in 1/2-13 UNC are a standard fastener in mechanical assemblies, structural connections, equipment mounting, and machinery repair across residential, commercial, and industrial settings. The fully threaded design maximizes thread engagement along the full shank length, making it well suited for shorter grip applications and through-bolt configurations. ASTM A354 BD compliance confirms minimum tensile and proof load performance for safety-critical joints.

Key Features

• Grade 8 steel construction for high tensile strength per ASTM A354 BD
• 1/2-13 UNC thread, fully threaded along the 1-3/4 inch length under head
• Zinc-plated finish for basic corrosion resistance
• Hex drive head for standard wrench and socket installation
• Sold in a 50-count package to support job-site and shop inventory needs

Compatibility

Designed as a standard 1/2-13 UNC hex head cap screw suitable for use with any 1/2-13 threaded nut or tapped hole conforming to UNC thread standards.

Installation Notes

Installation is performed with a standard 3/4 inch wrench or socket driver. Verify that the mating nut or tapped hole is also 1/2-13 UNC before installation. Follow applicable torque specifications from the equipment manufacturer or structural engineer of record for the assembly being fastened. Do not mix Grade 8 fasteners with lower-grade nuts or hardware in tensile-critical joints.
