Value Collection 701175PR Button Socket Cap Screw 3/8-16

Product Description

The VALUE COLLECTION 701175PR is a 3/8-16 x 2 inch button socket cap screw machined from alloy steel and finished with a black oxide coating. The button head profile presents a low-profile dome that reduces snag points in assemblies where clearance is limited. Drive engagement is through a 7/32 inch hex socket, requiring an Allen-style driver or bit. Thread form follows UNC (Unified National Coarse) standards and the screw is fully threaded along its 2 inch length under the head. Hardness is rated at 36 to 43 HRC, placing it in the range appropriate for high-strength fastener applications. Licensed machinists, millwrights, maintenance technicians, and fabricators are the typical end users.

This screw is suited for general industrial fabrication, machine assembly, jig and fixture construction, and structural panel attachment where a flush or low-profile fastener head is required. The black oxide finish provides a degree of corrosion resistance in dry or mildly humid indoor environments and reduces light reflection in optical or precision equipment assemblies. The 3/8-16 UNC thread class 3A fit ensures close tolerance engagement with standard tapped holes or nuts.

Key Features

• Button head, low-profile dome reduces clearance conflicts in tight assemblies
• 7/32 inch hex socket drive for Allen key or hex bit installation
• Fully threaded 2 inch length under head for maximum thread engagement
• Alloy steel construction with 36 to 43 HRC hardness rating
• Black oxide coating for mild corrosion resistance and reduced glare
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard UNC thread replacement or new-installation fastener for any tapped hole or nut accepting a 3/8-16 thread pitch, conforming to ANSI/ASME B18.3 and ASTM F835 specifications.

Installation Notes

Installation requires a 7/32 inch hex (Allen) key or matching hex bit and driver. Ensure the mating tapped hole or nut is clean and free of debris before threading. Apply appropriate thread lubricant or anti-seize if the application involves dissimilar metals or exposure to moisture. Torque to the value specified by the assembly engineer or applicable structural standard for 3/8-16 alloy steel fasteners in the given joint design.
