Value Collection -48409-5 Flat Socket Cap Screw 5 Pack

Product Description

The VALUE COLLECTION -48409-5 is a flat socket cap screw designed for bolted assemblies that require a flush or countersunk fastener profile. Featuring an 82-degree flat head with a 1/2-inch hex socket drive, this screw is fully threaded at 3/4-10 UNC and measures 4 inches in overall length. Constructed from alloy steel with a black oxide finish, it provides solid mechanical strength and moderate corrosion resistance in indoor or lightly controlled environments. It is sold in a package quantity of 5 and is suited for installation by machinists, millwrights, and mechanical contractors working on structural or equipment assemblies.

This fastener is appropriate for use in machinery, structural fixtures, tooling plates, and similar applications where a countersunk socket-drive fastener is required. The fully threaded shank allows engagement along the entire bolt length, making it well-suited for thinner material assemblies or through-bolt configurations. The 3/4-10 UNC thread standard ensures compatibility with standard tapped holes and nuts conforming to ASME/ANSI B18.3 and ASTM F835 specifications.

Key Features

• 82-degree flat head profile allows flush or countersunk installation in standard countersunk holes
• 1/2-inch hex socket drive for use with standard hex keys or socket drivers
• Fully threaded 3/4-10 UNC shank for maximum thread engagement
• Alloy steel construction provides high tensile and shear strength
• Black oxide finish for moderate corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM F835 fastener standards

Compatibility

Designed for use in standard countersunk 3/4-10 UNC tapped holes conforming to ASME/ANSI B18.3 dimensions. Suitable for alloy steel fastener applications requiring an 82-degree flat head socket cap screw in inch measurement configurations.

Installation Notes

Installation should be performed by a qualified mechanic, machinist, or millwright using a calibrated 1/2-inch hex key or socket drive tool. Ensure the receiving hole is properly countersunk to 82 degrees before installation. Torque to the fastener manufacturer or engineering specification for the assembly; do not exceed rated torque for the material and thread class. Inspect threads and seating surface for damage before installation.
