Value Collection R40684121 Hex Socket Cap Screw 1/2-13 Unc

Product Description

The VALUE COLLECTION R40684121 is a hex socket cap screw designed for secure fastening in mechanical, industrial, and structural applications. Threaded to a 1/2-13 UNC specification, it features a 1-1/4 inch length under the head and accepts a 3/8 inch hex drive key for installation. Constructed from 18-8 stainless steel, this fastener resists corrosion in wet, chemical-exposed, or outdoor environments. The socket cap head provides a low-profile, high-torque fastening solution suitable where a standard hex bolt head would interfere with adjacent components. Licensed machinists, millwrights, pipefitters, and general maintenance technicians commonly install this type of fastener.

This screw is suited for light to medium-duty assemblies requiring corrosion resistance. Typical applications include equipment frames, pump housings, pipe flanges, enclosures, and mechanical assemblies across residential, commercial, and industrial settings. The 1/2-13 UNC coarse thread provides reliable thread engagement in steel, aluminum, and other base materials. It is sold individually with a minimum order quantity of 5 units per transaction.

Key Features

• 1/2-13 UNC coarse thread for broad material compatibility
• 1-1/4 inch length under head for standard through-bolt and tapped-hole applications
• 3/8 inch hex socket drive for high-torque installation with a standard hex key or socket driver
• 18-8 stainless steel construction provides corrosion and oxidation resistance
• Low-profile socket cap head suitable for recessed or clearance-limited installations

Compatibility

Designed as a standard 1/2-13 UNC hex socket cap screw for use in any tapped hole or through-bolt application requiring 18-8 stainless steel material grade and a 3/8 inch hex drive.

Installation Notes

Installation is performed with a 3/8 inch hex key or socket driver. Verify that the mating thread is clean and free of debris before installation. Apply appropriate thread lubricant or anti-seize compound when joining stainless steel to stainless steel to prevent galling. Follow applicable mechanical codes and equipment manufacturer torque specifications for the assembly being serviced.
