Value Collection R57001076 Hex Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R57001076 is a hex socket cap screw designed for fastening applications that require a recessed drive and a flush or low-profile head. Threaded to a 1/2-13 UNC specification, this screw measures 6-1/2 inches in length under the head and accepts a 3/8-inch hex key drive. It is manufactured from 18-8 stainless steel with a bright, uncoated finish, making it well suited for environments where corrosion resistance is a priority. Machinists, millwrights, pipefitters, and maintenance technicians routinely specify socket cap screws of this type when access space limits the use of standard wrenches or when torque must be applied in confined clearances.

This screw is commonly used in industrial machinery, equipment frames, pipe flanges, pump housings, and structural assemblies across manufacturing, mechanical, and facilities maintenance environments. The 1/2-13 UNC thread form is a standard coarse-thread designation compatible with the full range of matching nuts, threaded inserts, and tapped holes produced to that specification. The 6-1/2-inch under-head length accommodates applications requiring fastener engagement through thicker material stacks or extended standoff distances.

Key Features

• 1/2-13 UNC coarse thread for broad hardware compatibility
• 6-1/2-inch length under head for deep engagement applications
• 3/8-inch hex socket drive for use with standard hex keys and drivers
• 18-8 stainless steel construction for corrosion resistance in wet or chemical-adjacent environments
• Bright, uncoated finish — no plating to add dimensional variability or interfere with thread fit
• Sold individually — single-piece minimum order quantity

Compatibility

Designed for use in any tapped hole or nut conforming to the 1/2-13 UNC thread standard. No specific equipment model compatibility was provided by the manufacturer for this fastener.

Installation Notes

Installation is typically performed by a machinist, millwright, or maintenance technician using a 3/8-inch hex key or socket driver. De-energize, depressurize, or lock out the equipment being serviced before removing or installing fasteners in mechanical or pressurized assemblies. Apply appropriate thread lubricant or anti-seize compound when torquing stainless fasteners into stainless tapped holes to reduce the risk of galling. Follow the applicable equipment manufacturer torque specifications and any relevant ASME or facility maintenance standards for the assembly.
