Value Collection 1008U188 Sheet Metal Screw 10 Round Head

Product Description

The VALUE COLLECTION 1008U188 is a size 10 Type U point round head sheet metal screw manufactured from Grade 18-8 stainless steel. It measures 1/2 inch in length under the head and is designed for fastening sheet metal and light-gauge assemblies in trade and industrial applications. The Type U point drives into pre-drilled or punched holes without requiring a separate tapping operation. Grade 18-8 stainless construction provides corrosion resistance suitable for environments where carbon steel fasteners would corrode prematurely. This screw conforms to ASME B18.6.3 and ASME B18.6.4 dimensional standards.

This fastener is used in HVAC ductwork fabrication, electrical enclosure assembly, plumbing equipment mounting, and general sheet metal work. The round head profile sits above the mating surface and distributes clamping load across a wider bearing area, making it appropriate for thinner gauge sheet stock. Installers in mechanical, electrical, and sheet metal trades use this screw for both field and shop fabrication tasks.

Key Features

• Grade 18-8 stainless steel construction resists corrosion in wet or chemically active environments
• Type U point for use in pre-drilled or punched sheet metal without a tap
• Round head profile provides broad bearing surface on thin-gauge material
• 1/2 inch length under head suits light-gauge sheet metal fastening
• Conforms to ASME B18.6.3 and ASME B18.6.4 dimensional standards
• Inch measurement system for compatibility with standard US tooling and hole charts

Compatibility

Designed as a standard inch-series sheet metal screw for use in light-gauge steel, aluminum, and similar sheet metal assemblies requiring a size 10 Type U round head fastener per ASME B18.6.3 and ASME B18.6.4.

Installation Notes

Sheet metal screws of this type are installed by sheet metal mechanics, HVAC technicians, and electricians using a standard Phillips or slotted driver matched to the head recess. Verify the correct hole size per manufacturer drill charts before driving to avoid stripping the Type U point engagement. De-energize any electrical enclosure and isolate any HVAC system before fastening panels or covers. Do not overtorque stainless steel fasteners, as galling can occur without proper lubrication or controlled torque application.
