U.S. Aluminum 105WBG #10 X 1½” Hi Hex Head Screw W / Rubber Washer, 100/Bag

Seal it and secure it in one step. U.S. Aluminum 105WBG fasteners combine a #10 × 1-1/2" self-tapping screw with a factory-fitted rubber sealing washer for tighter, cleaner gutter installs. The hi-hex washer head gives your 1/4" driver confident engagement, while the corrosion-resistant finish stands up to weather and washdowns. Ideal for fastening hangers, outlets, straps, and accessories where a leak-resistant connection matters. Packed 100 per bag to keep crews moving.

Features

• Integrated sealing washer: Rubber washer compresses under the head for a more watertight joint at gutters, outlets, and straps.
• #10 × 1-1/2" sweet spot: Versatile length for most 5" and 6" K-style hardware attachments.
• Hi-hex washer head: Positive 1/4" hex drive engagement with fewer cam-outs; seats flush for a clean look.
• Self-tapping point: Fast starts in wood fascia and compatible substrates—pilot typically unnecessary.
• Aggressive thread profile: High pull-out strength helps runs stay tight season after season.
• Exterior-rated coating: Corrosion-resistant finish for wet and coastal environments (use compatible metals).
• Contractor pack: 100/bag for efficient stocking and continuous production across long eaves.
• Multi-use fit: Pairs with hangers, outlets, straps, end caps, and other common K-style accessories.

Q: What substrates do these self-tapping screws work best in?
A: Wood fascia and common framing members; for very hard or brittle substrates, a small pilot hole can help reduce split-out.

Q: What driver bit and head style do they use?
A: A 1/4" hex driver fits the hi-hex (hex-washer) head for strong engagement and fewer cam-outs.

Q: How tight should I set them with the sealing washer?
A: Drive until the hardware seats and the rubber washer compresses uniformly to form a seal—avoid over-torqueing, which can squash or damage the washer.

Q: Are they suitable for wet or coastal environments?
A: Yes, they have a corrosion-resistant coating and a sealing washer for leak-resistant installs; pair with compatible gutter materials and quality sealant for maximum longevity.
