Round Head Machine Screw · #8-32 x 1/2 in - Zinc-Plated Steel - Combo Drive - Fasteners 8-32X1/2

What this product is for

This #8-32 x 1/2 in machine screw is used to fasten electrical goods such as covers, device hardware, small panels, and metal components that are tapped or matched with a #8-32 thread. The zinc-plated steel body is commonly selected for indoor electrical and general maintenance work.

Use for

• Electrical box and cover hardware where #8-32 thread is specified
• Panel and enclosure fastening
• General replacement of round head machine screws in indoor service work
• Applications needing a combo drive for slot or Phillips installation

Avoid for

• Applications where the exact OEM head style or drive type is unknown
• Outdoor or corrosive locations unless additional corrosion protection is required
• Threaded holes that require 6-32, 10-32, metric, or thread-cutting screws

Best for

Electricians and maintenance buyers looking for a common zinc-plated replacement screw in a #8-32 thread and 1/2 in length. This size is typically chosen when a 6-32 device screw is too small and a short machine screw is needed to avoid bottoming out behind covers or hardware.

Installed in

Typically installed in indoor electrical boxes, covers, enclosures, brackets, and similar metal hardware with matching #8-32 threads. Actual fit depends on the equipment manufacturer and thread condition.

Why this product exists

It provides a standard machine-thread fastener for electrical and general hardware assembly where a blunt-tip screw is preferred over a sharp-point sheet metal screw. Zinc plating helps resist light corrosion in normal indoor environments.

Compared with similar products

Compared with sheet metal screws, a machine screw is intended for pre-threaded holes or nuts rather than cutting its own thread. Compared with longer #8-32 screws, the 1/2 in length is commonly used where clearance is limited. Compared with slotted-only screws, a combo drive is typically easier to install with standard electrician hand tools. Head style and drive details should be confirmed against the application before purchase.
