Value Collection 48547 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION 48547 is a partially threaded hex socket cap screw designed for high-strength fastening applications where a recessed drive profile is required. Built from alloy steel and finished with a black oxide coating, this fastener meets ASME/ANSI B18.3 and ASTM A574 standards. The 1/2-13 UNC thread size and 9-inch length under head make it suitable for through-bolt and deep-reach clamping applications. The 3/8-inch hex drive accepts standard hex keys and Allen-type drivers. Sold in a pack of 5, this screw is a dependable choice for mechanical, industrial, and equipment assembly work.

This cap screw is used in general mechanical assembly, industrial fabrication, and equipment mounting where a flush or recessed fastener head is needed. The partially threaded shank provides a smooth grip zone that resists thread galling in clamped joints. The black oxide finish provides mild corrosion resistance and reduces glare in finished assemblies. Licensed tradespeople, machinists, and maintenance technicians commonly install this type of fastener in structural, machine tool, and equipment enclosure applications.

Key Features

• 1/2-13 UNC thread form for compatibility with standard unified coarse-thread tapped holes
• 9-inch length under head for deep-reach or through-bolt installations
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides mild corrosion resistance and surface hardness retention
• 3/8-inch hex socket drive works with standard hex keys and driver bits
• Partially threaded shank preserves a smooth grip zone for precision joint clamping

Compatibility

Designed as a standard-geometry hex socket cap screw for use in any 1/2-13 UNC tapped hole requiring a 9-inch partially threaded fastener per ASME/ANSI B18.3.

Installation Notes

Install using a 3/8-inch hex key or Allen-type driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread lubricant or anti-seize compound if required by the application or relevant industry standard. Do not exceed the rated proof load for ASTM A574 alloy steel socket cap screws.
