Value Collection 5020MPF Machine Screw 1/2-13x1-1/4 Flat Head

Product Description

The VALUE COLLECTION 5020MPF is a 1/2-13 UNC steel machine screw with a flat head and Phillips drive, finished in zinc for corrosion resistance. It measures 1-1/4 inches in overall length and is manufactured to ASME B18.6.3 and SAE J82 standards. The flat head profile sits flush with or below the mating surface when installed in a countersunk hole, making it well suited for applications where a low-profile fastener is required. At 0.064 pounds per piece, this screw is a standard inch-series fastener installed by machinists, millwrights, electricians, and general maintenance trades across industrial and commercial settings.

This fastener is used in general mechanical assembly, panel mounting, equipment enclosures, and structural framing applications where a 1/2-13 thread pitch and flush seating are specified. The zinc finish provides a base level of corrosion protection appropriate for indoor or sheltered environments. It is sold individually with a minimum order quantity of 5 pieces, making it suitable for both service-call restocking and larger maintenance projects.

Key Features

• 1/2-13 UNC thread for broad compatibility with standard inch-series tapped holes
• Flat head profile seats flush when installed in a countersunk hole
• Phillips drive for use with common hand and power tools
• Zinc finish provides corrosion resistance in dry or sheltered environments
• Meets ASME B18.6.3 and SAE J82 fastener standards
• Steel construction for reliable tensile and shear strength in mechanical assemblies

Compatibility

Designed as a standard inch-series replacement or service fastener for any application specifying a 1/2-13 UNC flat head Phillips machine screw to ASME B18.6.3 or SAE J82.

Installation Notes

Installation requires a properly countersunk or pre-tapped 1/2-13 hole in the mating material. Use a Phillips screwdriver or power driver bit sized for the fastener to avoid cam-out and head damage. Ensure the mating threads are clean and free of debris before driving. Follow applicable mechanical codes and torque guidelines for the assembly type and material being fastened.
