Value Collection 33662 Hex Socket Cap Screw 1/2-13 Unc 25 Pack

Product Description

The VALUE COLLECTION 33662 is a hex socket cap screw designed for high-strength fastening applications across industrial, mechanical, and trade installations. Sized at 1/2-13 UNC with a 1-inch length under head, this fastener is fully threaded and driven with a 3/8-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid tensile strength and moderate corrosion resistance in dry or lightly oiled environments. Sold in a pack of 25, it meets ASME/ANSI B18.3 and ASTM A574 standards, making it a dependable choice for structural and mechanical assemblies where torque and clamp load requirements are critical.

This screw is suited for use in machinery, equipment frames, jigs, fixtures, and general mechanical assemblies. The 1/2-13 UNC thread is a common coarse-thread specification found in a wide range of ferrous and non-ferrous base materials. Fully threaded construction makes it appropriate for through-hole applications and shorter clamping scenarios. Tradespeople in maintenance, millwright, and mechanical contracting work will encounter this size regularly in field and shop settings.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded along the 1-inch length under head for maximum thread engagement
• 3/8-inch hex drive accepts standard Allen keys and hex bit sockets
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw for use in any application requiring an ASME/ANSI B18.3 compliant fastener in that thread size and length.

Installation Notes

Installation is performed with a 3/8-inch hex key or Allen-head socket driver. Ensure the mating tapped hole is clean and free of debris before installation. Apply thread lubricant or threadlocker as required by the assembly specification. Follow applicable torque tables for 1/2-13 alloy steel fasteners and relevant codes such as ASME or equipment manufacturer guidelines.
