U.S. Aluminum 105BG #10 x 1-1/2 in. Hi Hex Head Screw Gutter Fastener, 100/bag

Built for speed and hold, the U.S. Aluminum 105BG fasteners bite cleanly into fascia and framing to lock gutter hangers, outlets, and accessories in place. The #10 × 1-1/2" length covers most K-style installs, while the hi-hex washer head gives your 1/4" driver positive engagement with fewer cam-outs. A corrosion-resistant finish stands up to weather so your runs stay tight season after season. Packed 100 per bag to keep crews moving.

Features

• #10 × 1-1/2" sizing: Versatile length for common hanger and outlet attachments.
• Hi-hex washer head: Strong driver engagement with a 1/4" hex; reduced cam-out.

• Aggressive thread profile: High pull-out resistance for secure, long-term installs.
• Corrosion-resistant coating: Exterior-rated finish for wet and coastal environments.
• Clean, professional finish: Low-profile head seats neatly against hardware.
• Contractor pack: 100/bag for efficient stocking and production across long eaves.
• K-style compatible: Ideal with 5" and 6" gutter hangers, outlets, and accessories.

Q: Will these screws work for both 5" and 6" K-style hangers and outlets?
A: Yes. They’re sized (#10 × 1-1/2") for common 5" and 6" K-style hangers, outlets, straps, and accessories.

Q: Do I need to pre-drill, or are they truly self-tapping?
A: They’re self-tapping and usually don’t require a pilot in typical wood fascia. For very hard or brittle substrates, a small pilot can reduce split-out.

Q: What driver bit should I use and how tight should I seat them?
A: Use a 1/4" hex driver on the hi-hex washer head. Drive until the hardware seats snug—avoid over-torqueing to prevent stripping or denting hardware.

Q: Are they corrosion-resistant enough for wet or coastal climates?
A: Yes. They have a weather-resistant coating. For harsh coastal exposure, pair with compatible corrosion-resistant gutter components and sealant best practices.
