Value Collection 011219P Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 011219P is a hex socket cap screw designed for fastening applications that require a recessed drive and high clamping strength. Threaded to the 5/16-18 UNC specification, this screw measures 3 inches in length under the head and features partial threading. The drive type is hex, accepting a 1/4 inch drive tool. Constructed from alloy steel with a black oxide finish coating, the 011219P meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for structural and mechanical assembly work where tensile strength and corrosion resistance matter.

This screw is used in general mechanical and industrial assembly where socket-head cap screws are specified. Typical applications include mounting fixtures, machine components, and assemblies requiring flush or recessed fastener heads. The black oxide coating provides mild corrosion resistance and reduces light reflection in finished assemblies. The screw is suitable for use in residential and commercial equipment fabrication, maintenance, and repair across mechanical, HVAC, and electrical trades. Minimum order quantity is 100 pieces.

Key Features

• 5/16-18 UNC thread size for broad compatibility with standard tapped holes
• 3 inch length under head with partial threading for secure clamping in through-hole applications
• 1/4 inch hex drive for use with standard hex keys and socket drivers
• Alloy steel construction meets ASTM A574 tensile strength requirements
• Black oxide finish coating for mild corrosion resistance and reduced glare
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style and replacement fastener for any application requiring a 5/16-18 UNC hex socket cap screw with a 3 inch length under head and partial threading.

Installation Notes

Installation is typically performed by mechanical, HVAC, or electrical technicians using a 1/4 inch hex key or socket driver. Always ensure the receiving threads are clean, properly tapped, and free of debris before driving the screw. Do not exceed the torque specifications called out in the equipment manufacturer's service documentation. Partial thread engagement requires sufficient thread depth in the mating component to achieve full clamping load.
