Value Collection 019351P Low Head Socket Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 019351P is a low head socket cap screw designed for applications where standard cap head height creates clearance problems. Manufactured from alloy steel with a black oxide finish, this fastener uses a 1/4-inch hex key drive and is fully threaded along its 3/4-inch length under head. The 1/2-13 UNC thread designation means coarse threading, which provides strong engagement in through-hole and tapped applications. Machinists, fabricators, and mechanical assembly technicians install this type of fastener where a reduced-profile head is required without sacrificing drive torque or holding strength.

This screw is suited for tight-clearance installations in mechanical assemblies, fixtures, tooling plates, and machine guarding where a standard socket cap head would interfere with adjacent components or mating surfaces. The black oxide finish offers mild corrosion resistance and reduces surface glare, making it a common choice in industrial and manufacturing environments. Fully threaded construction allows engagement from the first thread through the full shank length, giving flexibility in varying material thicknesses.

Key Features

• Low socket cap head profile reduces clearance requirements compared to standard socket cap screws
• Alloy steel construction provides high tensile strength for demanding mechanical assemblies
• Black oxide finish delivers mild corrosion resistance and a non-reflective surface
• Fully threaded along 3/4-inch length under head for maximum thread engagement
• 1/4-inch hex socket drive accepts standard hex keys and hex bit drivers
• Meets ASME/ANSI B18.8 fastener standard for dimensional consistency

Compatibility

Designed as a standard inch-series low head socket cap screw with 1/2-13 UNC coarse threading, suitable for tapped holes or through-bolt assemblies requiring a low-profile head and hex socket drive.

Installation Notes

Installation is performed by machinists or mechanical assemblers using a 1/4-inch hex key or hex bit driver. Ensure the tapped hole or nut thread specification matches 1/2-13 UNC before installation. De-burr and clean mating surfaces before seating the fastener to prevent galling on the alloy steel threads. Do not exceed the fastener's rated torque range for the alloy steel grade; consult published torque tables for the applicable property class.
