Value Collection MSC-67568840 Machine Screw 4-40 Unc

Product Description

The VALUE COLLECTION MSC-67568840 is a pan head machine screw designed for general fastening applications across mechanical, electrical, and light industrial assemblies. It features a 4-40 UNC thread specification and measures 0.25 inches in length under the head. The slotted drive accepts a standard flat-blade screwdriver for installation and removal. Manufactured from Grade 18-8 stainless steel, this screw resists corrosion in environments exposed to moisture or mild chemicals. No coating is applied, and no washer is included. It is suited for use by machinists, electricians, and maintenance technicians who require a reliable, corrosion-resistant fastener in compact thread sizes.

This screw is appropriate for residential and commercial applications where a small-diameter, fine-thread fastener is needed. Common uses include securing terminal blocks, circuit board hardware, enclosure panels, instrument housings, and other light-duty mechanical assemblies. The 4-40 UNC thread is a widely used standard size in electronics and instrumentation work. Sold individually, with a minimum order quantity of 100 pieces per order.

Installation Notes

Installation is performed with a flat-blade screwdriver matched to the slotted drive width. Ensure mating threads are clean and free of debris before driving. Do not overtighten in thin or soft mating materials, as pan head screws in fine thread sizes are susceptible to thread stripping. Follow applicable mechanical or electrical codes when used in regulated assemblies.
