What makes these 1/2Inch UNC Socket Cap Screws suitable for heavy-duty applications?

These 1/2Inch UNC Socket Cap Screws are made from Grade 12.9 high tensile alloy steel, ensuring maximum strength, resistance to shearing, and fatigue, making them ideal for heavy-duty structural and mechanical tasks.

How does the black oxide finish benefit these socket cap screws?

The black oxide finish provides a sleek, industrial appearance while offering added protection against minor abrasion, corrosion, and oil, helping to prolong the lifespan of the fasteners.

Can I use these 1/2Inch UNC Socket Cap Screws in tight spaces?

Yes, the deep hex socket drive in these screws allows for high-torque tightening in confined spaces where a standard wrench might not reach, making them perfect for constrained environments.

What are the technical specifications of these high tensile steel screws?

These screws have a 1/2-inch diameter, 1 1/2-inch length (excluding head), 13 threads per inch (coarse), and feature a 3/8-inch hex drive for easy installation with an Allen key, all made from Grade 12.9 alloy steel.

Are these socket cap screws suitable for automotive and machinery repairs?

Absolutely, these 1/2Inch UNC Socket Cap Screws are ideal for automotive suspension, engine mounts, industrial machinery, and high-vibration agricultural equipment due to their high tensile strength and reliable threading.

High Tensile 1/2Inch UNC Socket Head Cap Screws

Black Oxide Finish | Grade 12.9 Alloy Steel | Heavy-Duty Fasteners

These 1/2Inch UNC Socket Cap Screws are engineered for maximum strength and reliability in demanding structural and mechanical applications. Manufactured from Grade 12.9 high tensile alloy steel, these bolts provide a high-performance fastening solution where space is limited but high clamping force is essential.

The UNC (Unified Coarse) thread makes these ideal for use in heavy machinery, automotive repairs, and vintage equipment maintenance, particularly where deep thread engagement into cast iron or aluminum is required.

Key Performance Features

Grade 12.9 Tensile Strength: One of the highest strength classes available for threaded fasteners, ensuring resistance to shearing and fatigue.
Deep Hex Socket: The internal drive allows for high-torque tightening in tight spaces where a standard wrench cannot reach.
Black Oxide Finish: Provides a clean, industrial look and offers a layer of protection against minor abrasion and oil.
Precision UNC Thread: 1/2-inch diameter with standard 13 threads per inch (TPI) for a secure, rattle-free fit.
