Value Collection 33588 Hex Socket Cap Screw 8-32 Unc

Product Description

The VALUE COLLECTION 33588 is a fully threaded hex socket cap screw designed for precision fastening applications in mechanical assemblies, machine components, and structural joints. Sized at 8-32 UNC with a 1-1/4 inch length under head, this screw uses a 9/64 inch hex drive and is manufactured from alloy steel with a black oxide coating for corrosion resistance. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for applications that require controlled tensile strength and dimensional consistency. Machinists, maintenance technicians, and fabricators regularly specify this fastener type for both production and repair work.

This cap screw is suited for use in light industrial and commercial machinery, fixtures, enclosures, and equipment assemblies where a flush or countersunk socket drive is required. The 8-32 UNC thread is a coarse-pitch unified national thread commonly found in metal-to-metal fastening in moderate-load environments. The black oxide finish provides mild corrosion protection and reduces light reflection, making it appropriate for precision instruments and machinery housings as well.

Key Features

• 8-32 UNC thread for compatibility with standard tapped holes in metal assemblies
• 1-1/4 inch length under head for sufficient thread engagement in deeper applications
• 9/64 inch hex socket drive for use with standard hex keys and Allen wrenches
• Fully threaded shank provides maximum thread engagement along the full fastener length
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide coating provides mild corrosion resistance and a low-glare finish

Compatibility

Designed as a standard replacement or stock fastener for any application requiring an 8-32 UNC fully threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 9/64 inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the rated torque range for 8-32 alloy steel cap screws as specified by the applicable engineering standard or assembly drawing. Apply thread-locking compound if vibration resistance is required in the application.
