Value Collection MSC-74125485 Self Drilling Screw No. 14

Product Description

The VALUE COLLECTION MSC-74125485 is a No. 14 self drilling screw with a hex washer head and hex drive, manufactured from Grade 410 stainless steel. With a 1-1/4 inch length under head and a No. 3 drill point, this fastener is designed to drill its own pilot hole and tap threads in a single operation, eliminating the need for pre-drilling in light-gauge metal applications. The 410 stainless steel construction provides corrosion resistance suitable for outdoor and moisture-exposed environments. This screw is sold in multiples of 100 units per order.

This self drilling screw is used in light-gauge metal-to-metal and metal-to-substrate fastening applications common in HVAC ductwork, sheet metal fabrication, roofing, and general construction. The hex washer head provides a built-in bearing surface that distributes clamping load and resists pull-through. The No. 3 drill point is rated for thicker gauge material than smaller drill point sizes, making it appropriate for structural sheet metal connections encountered in commercial and residential mechanical installations.

Key Features

• No. 3 drill point drills, taps, and fastens in one pass — no pre-drilling required
• Grade 410 stainless steel construction for corrosion resistance in wet or outdoor environments
• Hex washer head provides integrated bearing surface to resist pull-through
• Hex drive accepts standard hex bit drivers and nut drivers for fast installation
• 1/4-14 thread size with 1-1/4 inch length under head suits medium-depth sheet metal assemblies
• Sold in multiples of 100 — suitable for production or service van stocking

Compatibility

Designed as a standard No. 14 hex washer head self drilling screw for use in light-gauge to medium-gauge sheet metal fastening applications where corrosion resistance is required.

Installation Notes

Installation is performed with a hex bit driver or hex nut driver at controlled torque to avoid stripping the self-tapped thread. Apply consistent, steady pressure to allow the drill point to engage before the threads begin cutting. Do not overdrive — the washer head seats flush and further driving can deform the bearing surface or strip the thread. In HVAC and sheet metal work, follow applicable SMACNA guidelines for fastener spacing and gauge compatibility.
