Stewart Fastener J0832MRCZ 8-32x2 Round Head Machine Screws Zinc 100

Product Description

The STEWART FASTENER J0832MRCZ is a jar of 100 zinc-plated, 8-32 x 2-inch round head combination drive machine screws designed for reliable mechanical fastening in trade and light industrial applications. The 8-32 thread designation indicates a number 8 diameter with 32 threads per inch (UNC/UNF coarse-pitch series), and the 2-inch length suits through-fastening in panels, brackets, and enclosures. The combination drive head accepts both slotted and Phillips drivers, reducing tool-change time on the job. The zinc plating provides basic corrosion resistance suitable for indoor and protected environments. Sold as a single jar of 100 pieces.

These machine screws are commonly used in HVAC equipment assembly, electrical panel work, control box fabrication, and general mechanical assembly where a standard 8-32 thread pattern is specified. The round head profile sits above the fastened surface, making it appropriate for applications where a low-profile or countersunk head is not required. Technicians in HVAC, electrical, and plumbing trades keep 8-32 hardware on hand for panel cover fastening, component mounting, and field repairs to manufactured equipment.

Key Features

• 8-32 thread pattern, 2-inch length — a widely specified size across HVAC, electrical, and mechanical assemblies
• Round head profile provides a raised bearing surface without countersinking
• Combination drive (slotted and Phillips) accepts multiple driver types
• Zinc plating for basic corrosion protection in indoor or protected installations
• Jar of 100 pieces supports bulk service use and reduces restocking frequency

Compatibility

Designed as a standard 8-32 UNC machine screw suitable for any application specifying an 8-32 x 2-inch round head fastener with zinc finish.

Installation Notes

Machine screws require a pre-tapped hole or a matching nut for proper engagement — do not drive into untapped material. Ensure the mating thread is also 8-32 before installation to avoid cross-threading or stripping. When used in electrical enclosures or panels, follow applicable NEC guidelines for hardware used in listed assemblies. Use the appropriate slotted or Phillips driver to avoid cam-out and head damage.
