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

Product Description

The VALUE COLLECTION -48547-1 is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assembly, structural fabrication, and industrial maintenance. Featuring a 1/2-13 UNC thread size and a 10-inch length under head, this screw is driven with a 3/8-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and surface hardness suited to demanding shop and field environments. The black oxide coating also reduces light reflection, which is useful in precision or optical assembly settings. This package contains 5 screws.

This hex socket cap screw is appropriate for applications requiring a recessed drive profile where wrench clearance is limited. The partially threaded shank provides a bearing surface that resists lateral shear loads, making it suitable for through-bolting structural components, mounting fixtures, and securing heavy equipment. The 1/2-13 UNC thread is a standard coarse-thread designation, compatible with common tapped holes and hex nuts across general industrial and MRO applications. Licensed machinists, millwrights, pipefitters, and maintenance mechanics are the typical installers.

Key Features

• 1/2-13 UNC coarse thread for broad compatibility with standard tapped holes and fastening hardware
• 10-inch length under head accommodates deep through-bolt and stacked-component installations
• Partially threaded shank improves shear resistance compared to fully threaded designs
• 3/8-inch hex drive allows use with standard allen keys and hex bit sockets
• Alloy steel construction provides high tensile strength per ASME/ANSI B18.3 and ASTM A574
• Black oxide finish adds surface corrosion resistance and reduces galling during installation

Compatibility

Designed as an OEM-style replacement or standard-stock hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 for use in general industrial, structural, and MRO fastening applications requiring a 1/2-13 UNC thread.

Installation Notes

Installation is performed by qualified mechanics, millwrights, or maintenance technicians using a 3/8-inch hex key or Allen bit. Ensure mating tapped holes or nuts are clean, free of debris, and properly sized for 1/2-13 UNC thread engagement before driving the fastener. Apply appropriate thread lubricant or anti-seize compound where required by the application or maintenance specification. Do not exceed the rated torque range specified by the engineering design, and never use impact tools at full torque on socket cap screws without confirming fastener grade compatibility.
