Quick Fastener with four double-ended 135 Degree 1/8 Pilot & 10mm Driver - (Pack of 100) - #1408
The Quick Fastener #1408 (Pack of 100) is a high-precision, multi-stage mechanical fastener engineered for the rigorous demands of industrial metal assembly. In sectors like HVAC ductwork, fire suppression enclosure fabrication, and heavy-duty cabinetry, the traditional drill-then-drive workflow is a significant drain on labor resources. The #1408 eliminates this redundancy by integrating a high-speed 1/8" pilot drill directly with a heavy-duty 10mm hex driver. This one-step logic allows technicians to penetrate thick-gauge metals and secure the fastener in a single, continuous motion, effectively cutting assembly time by up to 50%.
Manufactured from case-hardened, zinc-plated steel, the #1408 is designed to survive high-torque and high-heat self-drilling applications. Its unique double-ended utility matrix provides operational longevity unseen in standard self-tappers; if the primary drill point becomes dull after repeated use in stainless steel, the technician simply reverses the bit to access a fresh tip. For contractors, the #1408 is the definitive choice for maximizing minutes-per-fastener efficiency.
Self-Centering Split Point Logic
Most standard drill points feature a 118-degree angle, which is prone to walking across the surface of hard metals. The #1408 utilizes a 135-degree split point. This flatter angle engages more of the cutting edge immediately upon contact, preventing surface marring and ensuring the hole is perfectly axial. The split refers to the secondary relief grind on the chisel edge, allowing penetration the moment pressure is applied.
Case-Hardened Zinc Plating
During the drilling phase, friction generates localized temperatures that can exceed 400°F. The #1408 is case-hardened to a high Rockwell hardness (C-Scale) to ensure the cutting flutes do not burn up. The case-hardened zinc plating acts as a sacrificial barrier, providing essential corrosion resistance for fasteners installed in humid, grease-laden commercial kitchens or outdoor HVAC units.
Double-Ended Utility Matrix
In industrial sheet metal work, the drill point is the first part to fail. By providing a mirrored design, the #1408 effectively doubles the duty cycle of every unit, providing a significant ROI compared to single-ended alternatives.
Elimination of Tool-Change Fatigue
In high-volume assembly, changing from a drill bit to a driver bit for every hole creates micro-delays. Over 1,000 fasteners, these delays total several hours of lost labor. The 10mm hex head allows for a seamless transition from drilling to high-torque driving without removing the bit from the chuck.
High-Torque 10mm Interface
While many fasteners use small Phillips drives prone to stripping, the #1408 utilizes a high-torque 10mm interface. This provides massive surface area for the driver to grip, allowing the technician to apply the torque required to seat the fastener into 12-gauge or 10-gauge steel without tool slippage.
Standardization of Pilot Holes
By utilizing a fixed pilot drill integrated into the fastener, the #1408 ensures every hole is the exact diameter required for maximum thread engagement. This prevents over-drilling, which leads to loose fasteners and compromised structural integrity in vibrating ductwork.
- Fire Suppression Enclosures: Mounting stainless steel agent tanks and control boxes to structural metal frameworks.
- Heavy-Duty HVAC Ducting: Securing large-diameter galvanized ducts where structural vibration requires a high-torque, non-stripping fastener.
- Commercial Kitchen Exhaust Hoods: Joining heavy-gauge stainless steel sections where a precision, non-walking start is required.
- Industrial Metal Cabinetry: Assembling power-distribution boxes and mechanical enclosures in manufacturing environments.
- Property Maintenance: Serving as a universal service fastener for on-site repairs of metal safety infrastructure.

RPM Management Protocol
When drilling into stainless steel, use a high-torque, low-RPM setting. Excessively high RPMs can cause the zinc plating to melt and gum up the flutes, leading to premature dulling.
Axial Alignment Verification
Ensure the drill is held perfectly perpendicular to the surface. While the 135-degree point prevents walking, an angled start can put side-load stress on the tip, potentially snapping it in 10-gauge steel.
The Double-End Flip
If penetration time increases, it is a sign of cutting-edge fatigue. Reverse the bit to utilize the secondary tip. Do not re-sharpen; the factory-ground angle is calibrated for the hex-driver interface.
Corrosion Verification
In maritime or chemical processing environments, check the seated hex head for red rust during annual walkthroughs. Any damage to the plating should be touched up with cold-galvanizing spray.
Can I use the #1408 for aluminum assembly?
Yes. Because aluminum is a gummy metal, the 135-degree split point geometry is excellent at evacuating chips without the bit becoming clogged, a common problem with standard 118-degree bits.
Does this fastener require a specific 10mm socket?
The #1408 is compatible with any standard 10mm hex driver. However, for industrial assembly, using a magnetic nut setter is recommended to ensure the fastener remains stable during the high-speed drilling phase.
Why is double-ended utility important in a 100-pack?
Technicians often run out of sharp bits before they run out of fasteners. The double-ended utility matrix ensures the tool is always as ready as the supply, effectively providing the cutting capacity of 200 standard fasteners per box.
