Value Collection 019197PR Hex Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 019197PR is a low socket cap hex socket screw designed for applications requiring a lower-profile head than a standard socket cap fastener. Sized at 5/16-18 UNC thread with a 5/8-inch length measured under the head, this screw is fully threaded and driven with a 5/32-inch hex key. It is manufactured from alloy steel with a black oxide finish that provides moderate corrosion resistance and a dark, consistent appearance. Maintenance technicians, millwrights, machine builders, and general fabricators install this type of fastener where clearance above the fastener head is limited or where a flush-mount aesthetic is required.

This screw is suited for light-to-medium duty mechanical assemblies, jigs, fixtures, machine guards, and equipment panels where a reduced head height is necessary. The black oxide finish makes it a common choice for applications where surface glare must be minimized or where a finished, uniform look is preferred alongside other blacked hardware. The fully threaded shank maximizes thread engagement across the full grip length, which is particularly useful in shorter fastener lengths like this 5/8-inch configuration.

Key Features

• Low socket cap head profile reduces clearance requirements compared to standard socket cap screws
• Fully threaded shank maximizes thread engagement over the entire 5/8-inch length under head
• Alloy steel construction provides strength suitable for general mechanical assembly
• Black oxide finish offers mild corrosion resistance and low-glare appearance
• 5/32-inch hex key drive conforms to ASME/ANSI B18.8 fastener standard
• UNC thread form (5/16-18) ensures broad compatibility with standard inch-series tapped holes

Compatibility

Designed as an OEM-style replacement or direct-install fastener for any application requiring a 5/16-18 UNC low socket cap screw with a 5/8-inch length under head, conforming to ASME/ANSI B18.8.

Installation Notes

Installation is performed using a 5/32-inch hex key or Allen driver; use of a calibrated torque wrench is recommended to avoid overloading the alloy steel shank in blind-tapped holes. Ensure the mating threaded hole is clean and free of debris before driving the screw. Black oxide does not provide heavy corrosion protection, so additional lubrication or a corrosion inhibitor should be considered in wet or outdoor environments. Follow applicable mechanical assembly standards and equipment manufacturer torque specifications for the specific joint.
