The Simpson Wafer-Head Construction Screw #8 x 1-1/4" from Simpson Strong-Tie is a high-performance fastening solution engineered for speed, strength, and versatility across a wide range of interior and exterior construction tasks. Whether you're tackling cabinetry, framing, outdoor furniture, or general home improvement projects, this tan-colored screw delivers reliable pull-through resistance and effortless installation - no predrilling required.

Key Features

• Wafer Head with 0.418" diameter - provides strong pull-through resistance, keeping materials firmly seated and reducing surface tear-out in finish and structural applications alike.
• Patented SawTooth Point - eliminates the need to predrill, saving setup time and allowing faster starts even in dense or layered materials.
• T20 6-Lobe Drive - the six-lobe recess delivers superior bit engagement, reducing cam-out and making driving more secure, consistent, and fatigue-free.
• Serrated Threads with 0.80" thread length - grip aggressively into the material for a firm, locked connection that resists backing out over time.
• Quik Guard Coating - protects the fastener against corrosion, making this screw suitable for both interior and exterior applications including outdoor furniture and exposed framing.
• Tan color finish - blends naturally with common composite and wood surfaces, keeping fastener heads discreet in visible finish applications.

Why This Product

• The SawTooth point technology means you can drive directly into wood, composite, or similar substrates without stopping to predrill - a significant time saver on large or repetitive fastening jobs like framing or cabinetry installation.
• The Quik Guard Coating makes this a true dual-purpose screw - one fastener works equally well indoors and outdoors, reducing the need to stock separate interior and exterior fastener types.
• The 6-lobe T20 drive recess keeps the bit seated firmly during driving, cutting down on stripped heads and missed drives - especially valuable in overhead or awkward-angle applications.
• The wafer head profile sits flat and wide, distributing clamping force across a broader surface area for strong pull-through resistance without requiring a countersink - ideal for thin panels, sheathing, and furniture assembly.

Frequently Asked Questions

Do I need to predrill before driving this screw?

No. The patented SawTooth point is specifically designed to eliminate the need for predrilling, allowing for fast starts and easy driving directly into your work material - saving time on both small and large projects.

Is this screw suitable for outdoor or exposed applications?

Yes. The Quik Guard Coating provides corrosion resistance that makes this wafer-head construction screw appropriate for both interior and exterior use, including outdoor furniture and exposed framing environments.

What drive bit does this screw require?

This screw uses a T20 6-Lobe (Torx-style) drive recess. You will need a T20 driver bit to install it. The 6-lobe design helps prevent cam-out and keeps the bit seated securely during driving.

What applications is this screw best suited for?

This versatile #8 x 1-1/4" fastener is well suited for cabinetry, framing, outdoor furniture, and general home improvement projects. The wafer head provides strong pull-through resistance, and the serrated threads lock firmly into a wide range of materials.
