Value Collection 33584 Hex Socket Cap Screw 8-32 Unc Alloy Steel

Product Description

The VALUE COLLECTION 33584 is a hex socket cap screw designed for secure mechanical fastening in assemblies where a flush or recessed drive is required. Sized at 8-32 UNC with a 1/2-inch length under head, this screw is fully threaded and driven with a 9/64-inch hex key. It is manufactured from alloy steel and finished with a black oxide coating, which provides moderate corrosion resistance and a low-reflectance appearance. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for applications that require a recognized performance specification. Machinists, maintenance technicians, and assembly professionals working with light-gauge metal components, housings, and brackets are the typical installers.

This screw is suited for use in machine assemblies, enclosures, panels, and mechanical fixtures where an internal hex drive is preferred over an external hex or slotted head. The 8-32 UNC thread is a common unified coarse thread used in general-purpose metal fastening across HVAC equipment housings, electrical enclosures, and light mechanical assemblies. The black oxide finish is appropriate for indoor or low-moisture environments. The fully threaded shank provides maximum thread engagement across the entire fastener length.

Key Features

• 8-32 UNC thread for common unified coarse thread compatibility
• 1/2-inch length under head with full threading along the entire shank
• 9/64-inch hex socket drive for use with standard hex keys or Allen wrenches
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides low-reflectance surface and moderate corrosion resistance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a general-purpose socket cap screw for use in any application requiring an 8-32 UNC internal hex drive fastener with a 1/2-inch length under head in alloy steel.

Installation Notes

Install with a calibrated or standard 9/64-inch hex key or T-handle driver. Ensure mating threads are clean and free of debris before installation. Do not overtighten, as alloy steel screws in smaller diameters can be susceptible to thread stripping in softer base materials. Refer to applicable assembly specifications for torque requirements based on joint material and application.
