1-1/2 in White Hex Head Sealing Washer Screw — 250 Pack

The Wrong Screw Turns a Clean Gutter Job Into a Callback

Loose straps, stripped heads, mismatched screw color, crushed washers, poor sealing contact, wrong fastener length, and rust-stained hardware can make a professional gutter install look rushed and create repair problems that should have been avoided.

This 1-1/2 in white hex head sealing washer screw helps solve that jobsite problem: the 1/4 in hex head supports solid driver engagement, the integrated washer helps distribute pressure and support sealing contact, the white finish blends with white exterior materials, and the 250 pack keeps crews moving without digging through random fastener bins.

Key Benefits at a Glance

Built for Gutter Fastening, Exterior Trim, and Light Sheet-Metal Work

This listing is for a 250 pack of 1-1/2 in white #10 hex head sealing washer screws. The uploaded product information identifies the screw as a 1-1/2 in length fastener with #10 diameter, 1/4 in hex head, integrated washer, Type 17 point, and white finish for gutter-related exterior fastening work.

For gutter installers, the value is simple: fewer mismatched fasteners, better driver engagement, cleaner visible hardware, and washer contact that helps finish the connection properly when the screw is installed in the right substrate at the right torque.

Use these screws for compatible gutter hardware, downspout straps, light trim, flashing, siding, fascia details, and sheet-metal-to-wood fastening where the screw length, point style, coating, washer, and substrate match the job.

Why This Screw Matters on a Real Gutter Job

Gutter crews do not need a mystery screw. They need a fastener that matches the visible finish, bites properly into the intended substrate, holds hardware in place, and does not create a messy washer or overdriven head problem.

The hex washer head design supports better driver engagement than many small Phillips-style exterior screws. The integrated washer helps distribute clamping pressure and support sealing contact. The Type 17 point supports faster starts in compatible materials, especially when fastening light metal to wood or similar substrates.

The strongest buying decision is not just “white screw.” It is confirming the screw length, driver size, washer fit, substrate, finish match, and installation pressure before the screw goes into the gutter system.

Contractor Applications

How the Screw Works

The Type 17 point helps the screw start into compatible materials and clear chips as it drives. The screw threads pull the fastener into the substrate, the 1/4 in hex head transfers torque from the driver, and the integrated washer helps spread clamping force around the fastener head.

The washer should be seated firmly enough to make contact without being crushed, split, or over-compressed. Overdriving can damage the washer, deform thin metal, strip the substrate, or reduce the quality of the seal. Underdriving can leave the washer loose and reduce contact.

Product Specifications

Who Uses These Screws?

Setup and Application Guide

1. Confirm the application is compatible with a #10 x 1-1/2 in hex washer head screw.
2. Confirm the substrate can accept the screw and that the fastener length is appropriate for the material stack.
3. Confirm the white finish matches or complements the visible gutter, trim, siding, or hardware area.
4. Use the correct 1/4 in nut setter or hex driver for the screw head.
5. Set driver torque so the screw seats firmly without crushing the washer.
6. Align the bracket, strap, trim piece, flashing, or accessory before driving the screw.
7. Drive the screw straight so the washer seats evenly against the surface.
8. Stop when the washer makes firm contact; do not overdrive, strip, or deform the material.
9. Check that the fastened part is secure and that the washer is not split, crushed, or cocked.
10. Inspect exposed fasteners during maintenance and replace damaged, corroded, loose, or overdriven screws as needed.

Pro Tip

Use a magnetic 1/4 in nut setter and controlled torque. The goal is a firm washer seat, not a flattened washer. A fast screw driven badly still becomes a callback.

Frequently Asked Questions

Fastener Safety and Installation Notice

Use eye protection and gloves when installing screws. Sharp points, metal shavings, driver slip, and over-torqued fasteners can cause injury or damage to the work surface.

Do not overdrive the screw. Crushing the washer, stripping the substrate, or deforming thin metal can reduce holding quality and sealing contact.

Confirm compatibility before use. This screw is not a structural fastener and should not be used for load-bearing, masonry, concrete, heavy steel, or engineered applications unless the project specification approves it.

Need Help Matching the Screw to the Job?

The right fastener depends on material thickness, substrate, finish, washer contact, driver size, and whether the screw is fastening gutter hardware, trim, flashing, siding, or light metal. Website chat is the fastest way to confirm fit before checkout.
