Value Collection R63062849 2-56 Flat Head Slotted Machine Screw

Product Description

The VALUE COLLECTION R63062849 is a 2-56 x 1/4 inch flat head slotted machine screw made from 18-8 stainless steel with a bright, uncoated finish. This screw uses a unified coarse thread (UNC) pattern and measures 1/4 inch in overall length as well as 1/4 inch under the head. The flat head profile sits flush with or countersunk into mating surfaces, making it a common choice in panels, enclosures, and assemblies where a low-profile fastener is required. Machinists, electricians, and assembly technicians install this type of hardware in light-duty mechanical and electrical applications where corrosion resistance is a priority.

This screw is suited for use in residential and commercial electrical panels, HVAC control boards, small appliance assemblies, and similar applications where a compact, corrosion-resistant threaded fastener is needed. The 2-56 thread size is a fine-pitch designation commonly found in instrumentation, electronics enclosures, and light sheet-metal work. Sold individually by package quantity of 1, with a minimum order quantity of 100 units per order.

Key Features

• 18-8 stainless steel construction provides corrosion and oxidation resistance
• Flat head design allows flush or countersunk seating in mating surfaces
• Slotted drive is compatible with standard flat-blade screwdrivers
• Bright, uncoated finish with no added plating or coating
• Inch-system UNC thread for compatibility with standard tapped holes in that size
• No washer included; washer-free installation

Compatibility

Designed as an OEM-style replacement or standard fastener for any application requiring a 2-56 UNC thread, 1/4 inch length, flat head, slotted machine screw in stainless steel.

Installation Notes

Installation is typically performed by machinists, electricians, or assembly technicians using a flat-blade screwdriver sized to the slotted drive. Ensure the mating hole is properly tapped or threaded for 2-56 UNC before driving. Do not overtighten, as the small diameter and fine thread pitch can lead to thread stripping in soft mating materials. Derate torque expectations when threading into aluminum, plastic, or other materials softer than stainless steel.
