Value Collection MP33833 No 10 Self Drilling Screw 1 Inch

Product Description

The VALUE COLLECTION MP33833 is a No. 10 self-drilling screw designed for fast, reliable fastening in light-gauge steel and sheet metal applications. It features a hex washer head with a hex drive, allowing installation with a standard nut driver or hex-bit driver. The screw measures 1 inch in length under the head and uses a No. 3 drill point, which cuts its own pilot hole without requiring pre-drilling. The zinc-plated steel construction provides basic corrosion resistance for general-purpose use in mechanical, HVAC, electrical, and plumbing applications where a secure, vibration-resistant fastener is needed.

This screw is commonly used by HVAC technicians, sheet metal workers, electricians, and plumbers for attaching ductwork flanges, junction box covers, equipment panels, and light structural sheet metal components. The hex washer head seats flush and spreads clamping load across the material surface. At 1 inch length under head, it suits single-layer or light double-layer sheet metal assemblies. This fastener ships in a minimum order quantity of 50 pieces per package.

Key Features

• No. 3 drill point eliminates the need for pre-drilling in light-gauge steel
• Hex washer head provides broad bearing surface and positive seating
• Hex drive compatible with standard nut drivers and hex-bit power tools
• Zinc-plated steel construction offers general-purpose corrosion resistance
• 1 inch length under head suits single-layer sheet metal and panel work
• Minimum order quantity of 50 ensures job-site supply availability

Compatibility

Designed as a general-purpose self-drilling fastener for light-gauge steel sheet metal assemblies in HVAC, electrical, and mechanical trade applications.

Installation Notes

Installation is performed with a hex-bit driver or nut driver at controlled speed to avoid stripping the drill point before it penetrates the substrate. Power down or de-energize any equipment panel before fastening near live electrical components. Do not overdrive the screw, as the hex washer head can deform and lose clamping effectiveness in thin gauge material. Follow applicable codes such as the Sheet Metal and Air Conditioning Contractors National Association (SMACNA) guidelines for duct assembly fastener spacing where required.
