Value Collection R52001132 Flat Head Phillips Machine Screw

Product Description

The VALUE COLLECTION R52001132 is a flat head Phillips drive machine screw designed for general mechanical fastening applications. Manufactured from steel with a zinc-plated finish for basic corrosion resistance, it features a 5/16-18 unified coarse thread and measures 1-1/2 inches in overall length. The countersunk flat head sits flush with or below the surface of the mated material when installed in a properly prepared countersunk hole. This fastener meets ASME B18.6.3 and SAE J82 standards, confirming dimensional and material compliance for use in commercial and industrial assemblies where a standardized inch-series machine screw is required.

This screw is suited for attaching panels, brackets, covers, and structural components in light to medium-duty mechanical assemblies. The 5/16-18 coarse thread engages quickly and resists cross-threading in field conditions, making it a common choice for maintenance, repair, and original equipment manufacturing work. The zinc plating provides a basic protective layer suitable for indoor and sheltered environments. It is sold in multiples of 50 units per order and packaged as a single unit quantity per pack.

Key Features

• 5/16-18 unified coarse thread for broad hardware compatibility
• 1-1/2 inches overall length with full-length threaded shank
• Flat countersunk head profile for flush or below-surface installation
• Phillips drive for standard power and hand tool compatibility
• Zinc-plated steel finish for basic corrosion resistance in sheltered environments
• Meets ASME B18.6.3 and SAE J82 dimensional and material standards

Compatibility

Designed as an OEM-style replacement or maintenance fastener for mechanical assemblies requiring a 5/16-18 coarse thread, flat head, Phillips drive machine screw conforming to ASME B18.6.3 and SAE J82 specifications.

Installation Notes

Installation is performed by maintenance technicians, millwrights, or assembly workers using a Phillips screwdriver or appropriate power driver bit. The receiving material should be tapped or fitted with a threaded insert to the 5/16-18 specification, and a countersink should be prepared to match the flat head angle when a flush finish is required. De-energize and lock out any equipment before replacing fasteners in live assemblies. Avoid overtightening, which can strip threads in softer base materials.
