Value Collection 0308MSR 3-48 X 0.5in Round Head Slotted Machine Screw

Product Description

The VALUE COLLECTION 0308MSR is a 3-48 thread, round head, slotted drive machine screw made from steel with a zinc finish. It measures 0.5 inches in length under the head and conforms to ASME B18.6.3 and SAE J82 standards. This fastener is designed for use in light-duty mechanical assemblies where a low-profile round head and a standard slotted drive are appropriate. It is commonly installed by electricians, HVAC technicians, and mechanical contractors working with control panels, enclosures, or light-gauge metal assemblies.

This screw is suited for residential and commercial applications requiring a fine-thread 3-48 fastener in steel with corrosion-resistant zinc coating. Typical use cases include securing terminal blocks, cover plates, and small components inside electrical panels, HVAC equipment housings, and similar light-gauge assemblies. It is sold in multiples of 100 pieces per order, with each package containing 1 unit of that quantity.

Key Features

• 3-48 thread size for fine-thread engagement in light-gauge materials
• Round head profile provides a low, finished appearance flush to the work surface
• Slotted drive compatible with standard flat-blade screwdrivers
• Steel construction with zinc finish for basic corrosion resistance
• Meets ASME B18.6.3 and SAE J82 fastener standards
• No washer included; designed for direct head-to-surface clamping

Compatibility

Designed as a standard inch-series machine screw for use in any application requiring a 3-48 thread, round head, slotted fastener per ASME B18.6.3 specifications.

Installation Notes

Install with a flat-blade screwdriver sized to fit the slotted head to avoid cam-out and head damage. De-energize any electrical equipment before installing or removing fasteners inside live panels or enclosures, in accordance with NFPA 70E lockout/tagout requirements. Do not exceed the clamping torque appropriate for a 3-48 steel screw in the mating material; over-torquing can strip the fine threads or crack light-gauge substrates.
