Value Collection SBRI02503000-050BX Machine Screw 1/4-20

Product Description

The VALUE COLLECTION SBRI02503000-050BX is a 1/4-20 UNC machine screw with a round head and slotted drive, manufactured from Grade 2 steel with a zinc-plated finish. Measuring 3 inches in length under the head, this fastener is designed for general-purpose mechanical assembly and light structural fastening. The zinc plating provides basic corrosion resistance suitable for indoor and sheltered applications. Sold in a minimum order quantity of 50 pieces, this screw is a standard inch-system fastener used across a wide range of trade and industrial applications.

This machine screw is commonly used in HVAC panel assembly, electrical enclosure fabrication, plumbing equipment mounting, and general equipment repair where a 1/4-20 UNC thread is specified. The round head profile sits above the mating surface and is well suited for through-hole applications where a low-profile head is not required. The slotted drive is compatible with standard flat-blade screwdrivers. This fastener ships without a washer and requires a matching nut or tapped hole for installation.

Compatibility

Designed as a standard 1/4-20 UNC inch-system machine screw compatible with any tapped hole or hex nut matching the 1/4-20 thread specification.

Installation Notes

Installation requires a matching 1/4-20 UNC tapped hole or nut. Use the appropriate flat-blade screwdriver or slotted power bit sized for the head to avoid cam-out and head damage. Apply fastener torque consistent with Grade 2 steel limits for this thread size. Ensure mating surfaces are clean and free of debris before driving the screw to achieve proper clamp load.
