Value Collection MP33829-1 No. 8 Self Drilling Screw 50pk

Product Description

The Value Collection MP33829-1 is a No. 8, 2-point self drilling screw with a hex washer head and hex drive, measuring 1/2 inch in length under the head. Manufactured from grade 1016/1024 steel with a zinc-plated finish, this screw is engineered to drill its own pilot hole and form threads in a single operation. The hex washer head provides a built-in bearing surface that resists pull-through, while the hex drive allows high-torque installation with standard hex bit drivers. Minimum order quantity is 50 pieces. These screws are commonly installed by sheet metal fabricators, HVAC technicians, and general contractors for metal-to-metal fastening applications.

The MP33829-1 is suited for light-gauge sheet metal assembly, HVAC duct work, metal framing, and similar applications where pre-drilling is impractical or inefficient. The 2-point drill tip is designed for thinner gauge steel, allowing clean penetration without deforming the workpiece. The zinc-plated finish provides a baseline level of corrosion resistance for interior or sheltered installations. Sold in a minimum quantity of 50, these screws are appropriate for service technicians, fabrication shops, and contractors who keep standard fastener inventory on hand.

Key Features

• No. 8 size with 2-point self drilling tip for single-step fastening in light-gauge steel
• 1/2 inch length under head for shallow-profile metal-to-metal connections
• Hex washer head provides integrated bearing surface and resists pull-through
• Hex drive compatible with standard hex bit drivers for high-torque installation
• Grade 1016/1024 steel construction meets AISI, ASME B18.6.3, and SAE J78 standards
• Zinc-plated finish for basic corrosion resistance in interior applications

Compatibility

Designed as a standard No. 8 hex washer head self drilling screw suitable for light-gauge sheet metal fastening applications where a 2-point drill tip and 1/2 inch under-head length are specified.

Installation Notes

Installation is performed by sheet metal workers, HVAC technicians, or general contractors using a hex bit driver or drill driver set to a controlled clutch setting to avoid over-driving. Always ensure the base material gauge is appropriate for the 2-point drill tip before installation. Follow applicable codes such as SMACNA duct construction standards for HVAC applications. Wear appropriate eye protection when driving self drilling screws into metal substrates.
