Value Collection R52001312 8-32x4 Round Head Machine Screw

Product Description

The VALUE COLLECTION R52001312 is a #8-32 machine screw measuring 4 inches in length under head, featuring a round head with combination slotted and Phillips drive. Manufactured from steel with a zinc-plated finish, it meets ASME B18.6.3 and SAE J82 standards for dimensional accuracy and mechanical performance. This fastener is intended for general mechanical assembly applications across industrial, commercial, and trade environments. Installation is straightforward with either a flat-blade or Phillips screwdriver. Sold individually per package with a minimum order quantity of 100 units.

This machine screw is suited for light-gauge metal panel assembly, electrical enclosure mounting, HVAC equipment housings, and general mechanical fastening tasks where a #8-32 thread is called out. The zinc-plated finish provides basic corrosion resistance in dry or lightly humid indoor environments. The combination drive allows use with either a standard flat-blade or Phillips screwdriver, reducing the chance of a drive mismatch on the job.

Key Features

• Thread size #8-32 UNC for broad compatibility with standard tapped holes and hex nuts
• 4-inch length under head for deeper engagement in stacked panels or thick substrates
• Round head profile distributes clamping load across a wider bearing surface
• Combination slotted and Phillips drive accepts both flat-blade and Phillips drivers
• Zinc-plated steel finish meets ASME B18.6.3 and SAE J82 standards
• Without washer style — clean install directly against mating surface

Compatibility

Designed as a standard #8-32 UNC machine screw suitable for pre-tapped holes, threaded inserts, or use with a matching hex nut in general mechanical, electrical, and HVAC enclosure assembly applications.

Installation Notes

This fastener is installed by mechanical, electrical, or HVAC technicians during panel and enclosure assembly. Power down any equipment before fastening or removing screws on live electrical enclosures, following NEC requirements. Use the correct driver bit size to avoid cam-out and damage to the drive recess. Do not overtorque into thin sheet metal or plastic standoffs, as the 4-inch length may extend through thinner assemblies.
