Lock Down Gutter Runs with 12 x 3 in Hex Washer Screws
A contractor-size 250-pack of 12 x 3 inch hex washer screws for compatible gutter, downspout, flashing, fascia, trim, roofing-panel, and exterior fastening work where length, washer seating, and driver control matter.

Compatibility Check Required
Fasteners Are Small Until One Backs Out, Leaks, Strips, or Rattles
Gutter and exterior work can lose time fast when the crew is fighting short screws, stripped heads, loose downspout straps, under-driven washers, over-crushed washers, or fasteners that do not match the material stack. The result is a slower install, messy rework, and details that can become callbacks.
These 12 x 3 in hex washer screws are built for that jobsite reality: a longer washer-head fastener in a 250-piece pack, ready for compatible gutter runs, fascia details, downspout parts, flashing, trim, and exterior metal connections when the substrate and point type are verified first.
Built for Gutter Crews That Need More Than a Small Repair Pack
12 x 3 in Fastener
A longer 12 screw for compatible fastening points where a short screw is not enough. Confirm the material stack and embedment before installation.
Hex Washer Head
The hex head works with a compatible nut setter or socket for controlled driving and stronger tool engagement than many shallow drive styles.
Bonded Sealing Washer
The washer helps distribute pressure under the head and supports a cleaner sealed fastening point when seated flat and not over-compressed.
250-Piece Bulk Pack
A practical quantity for contractors, service trucks, repair teams, and projects where a small handful of screws will not cover the work.
Made for the Fastening Details That Hold the Gutter System Together
This listing is for a 12 x 3 inch hex washer head screw with integrated washer in a 250-piece pack. The uploaded product content identifies the fastener as a 12 x 3 in professional hex head washer screw with silver coating, integrated washer, multi-purpose use, and 250-piece bulk pack. The uploaded image shows a silver hex washer head screw with a black bonded washer and sharp threaded point. :contentReference[oaicite:2]{index=2}
For gutter installers, the value is not hype about maximum holding power. The value is practical: a longer washer-head fastener that can help secure compatible gutter components, downspout straps, fascia details, flashing, trim, and exterior sheet-metal connections when the screw length, point type, driver, and material stack are correct.
Public product references confirm that hex washer head exterior screws are commonly used for roofing, HVAC, steel framing, gutters, flashing, wall panels, and sheet-metal fastening. Hex washer head designs also provide a larger bearing surface that helps distribute applied force over the fastened material. :contentReference[oaicite:3]{index=3}

The Real Pain Point Is Not the ScrewIt Is the Wrong Screw in the Wrong Stack
A 3 inch washer-head screw can be useful, but only when the job actually needs that length. Too short can fail to bite where it needs to. Too long can interfere behind the material. The wrong point can skate, split, strip, or require pre-drilling. The wrong torque can leave the washer loose or crush it until it no longer seats cleanly.
This listing keeps the buyer focused on the decisions that protect the job: screw length, 12 size, washer seating, driver size, substrate, point type, corrosion compatibility, and whether the fastener is going into fascia, metal trim, downspout hardware, flashing, or another exterior component.
The best result comes from test-driving the first screw in the actual material stack, checking washer compression, and confirming the head is seated without stripping, crushing, or deforming the surrounding material.
Where This 250-Pack Creates the Most Value
How the Hex Washer Head Screw Works
A hex washer head screw is driven with a compatible nut setter or socket. The hex head gives the driver more surface contact, while the washer under the head spreads pressure and helps protect the fastening point when it is seated correctly.
For gutter-related use, the installer should confirm the screws point type, pilot-hole needs, screw length, substrate, driver size, and washer compression before starting the full run. If final packaging confirms self-tapping or self-drilling performance, that language can be added accurately. Without that confirmation, the safest production wording is sharp-point exterior hex washer screw.
Choose the Fastener Based on the Job, Not the Hype
This Product: 12 x 3 in Washer Head
Best when the job needs a longer 12 exterior screw, hex drive control, a bonded washer, and a 250-pack contractor quantity.
Shorter Gutter Screw
Better when the material stack is thin, clearance is limited, or a 3 inch screw would be longer than the assembly needs.
Specialty or Stainless Fastener
Better when the application requires stainless steel, structural approval, manufacturer-specified hardware, color-matched heads, or a verified TEK drill point.

- Select the correct nut setter, socket, or hex driver for the screw head.

Pro Tip
Watch the washer, not just the head. The clean install happens when the washer sits flat and snug. A washer left loose can gap; a washer crushed flat can lose the clean seating that made the fastener worth using.
Frequently Asked Questions
What are 12 x 3 in hex washer screws used for?
They are used for compatible exterior fastening work, including gutter, downspout, flashing, trim, fascia, roofing-panel, HVAC, and sheet-metal applications where 12 size, 3 inch length, washer seating, and material compatibility are correct.
Are these self-drilling or self-tapping screws?
The uploaded draft uses self-tapping language, but the uploaded image alone does not confirm a TEK-style self-drilling point. Confirm the final package or supplier spec before publishing self-drilling, self-tapping, or no-pre-drill claims for specific materials.
Why does the washer matter?
The bonded washer helps distribute pressure under the head and supports a cleaner sealed fastening point when installed correctly. It should sit flat and snug without being left loose or crushed from over-torque.
When should a 3 inch screw be used instead of a shorter screw?
Use a 3 inch screw only when the material stack and substrate require that length. If the assembly is thin or clearance is limited, a shorter fastener may be the better choice.
What is GutterAll’s return policy for this product?
GutterAll offers a 30-day return window for unused products in original condition. Opened, used, driven, damaged, mixed, weathered, or altered fasteners may not be returnable unless defective. Customers should confirm length, point type, washer type, quantity, and compatibility before ordering.
What shipping and fulfillment options are available?
In-store pickup, local delivery, and nationwide shipping are available through Shopify checkout for eligible fastener orders. For project quantities, confirm packaging, quantity, and fulfillment options before checkout.
Fastener and Jobsite Safety Notice
Use eye protection, gloves, ladder safety, stable footing, and proper fall-prevention practices when installing gutter and exterior fasteners. Sharp screw points, cut metal, flashing, gutters, and downspout parts can cause injury.
Do not over-drive washer screws. Over-compressed washers can deform, split, or reduce sealing performance. Under-driven washers can leave gaps under the head.
Do not use these screws for engineered structural connections, incompatible metals, underwater applications, or manufacturer-specified assemblies unless the fastener is approved for that use.
Need Help Confirming the Right Fastener Before Checkout?
The right screw depends on length, washer type, point style, substrate, exposure, driver size, torque, and the part being fastened. Website chat is the fastest way to confirm the setup before ordering.
