Jake Sales 10 x 1-3/4" White Composite Decking Screws. Exterior Coated, Pressure Treated and ACQ Lumber Compatible. Use T20 Torx/Star Dive Bit - 1 Pound ~130 Screws

Why I reached for these screws

I’ve installed more than my share of composite decking, fascia, and railing, and the right fastener can make the difference between a clean finish and a mess of mushrooming and stripped heads. For a recent fascia refresh and a couple of small cap-stock repairs, I put the Jake Sales 1-3/4 in. white composite decking screws to work. They’re a #10 diameter screw with a T20 Torx drive, a Type 17 tip, dual fine/coarse threads, and a 10° diminishing head designed to minimize mushrooming in composite. On paper, they check all the boxes for synthetic trim and deck accessories, and the 1 lb box (about 130 screws) is a practical quantity for modest projects.

Design details that matter in composite

• T20 Torx head: The T20 star drive is a smart choice for composites. It resists cam-out better than Phillips or square, which is important when you’re driving into dense material and need consistent, straight pressure. Across my install, I didn’t round a single head or strip a bit.

• Type 17 tip: This self-tapping point starts cleanly and reduces walking. In most fascia and railing applications, I didn’t need to pre-drill. The tip bites predictably, even when starting at a slight angle to catch a layout line. Near the ends of a board or in colder conditions, I still prefer a small pilot or at least a countersink to control the finish.

• Dual thread and reversing threads: The lower coarse/fine thread pairing moves material efficiently; the upper reversing thread is there to cut down on mushrooming as the head seats. When everything is sized correctly, it does reduce that raised halo around the head that composite can leave. However, it also means you need to pick the right length so those reversing threads don’t engage too early.

• Diminishing head: The 10° head profile is subtle but effective. It’ll draw in neatly without insisting on a huge countersink, and the head diameter (about 0.266 in.) leaves a tidy footprint. If you’re aiming for a plug-and-play fascia plug system, the shorter length pairs well, and the head shape sits predictably in a countersink.

• Coating and corrosion resistance: The exterior coating is rated for 1200 hours of salt spray, and the screws are compatible with ACQ/pressure-treated lumber. I left a few driven through a cut-off into a PT scrap outdoors for a week of rain and morning dew; no red rust, and only slight dulling of the white finish on the head. For coastal decks, I’d always weigh stainless for critical structural pieces, but for fascia, rails, and cap stock, this coating is more than serviceable.

Real-world performance

I used these primarily on composite fascia and a section of PVC railing trim, with some test drives into cap-stock decking offcuts. In fascia, the screws performed as intended: fast starts, steady draw, and minimal surface disruption once I dialed in the technique. On the PVC trim, they cut crisp threads and seated without splitting or spiraling the material.

On dense cap-stock, technique mattered more. If I drove at full speed with a high-torque impact, the screw could stall just as the head began to seat, especially if the length was marginal for the stackup (for example, 3/4 in. fascia over thin backing). The upper reversing threads will lock the board to the screw; if there isn’t enough tip still advancing into the substrate, you can end up shy of fully flush. Switching to drill/driver mode, using a clutch setting, and driving at a moderate, steady speed solved this. In a couple of tough spots, a shallow clearance hole in the fascia (not the substrate) ensured the lower threads continued to advance and let the head seat cleanly.

As for removal, they back out cleanly in most cases. If you’ve seated the reversing threads tightly into the composite, removal can require a moment of forward pressure to break free before reversing. That’s normal with this style of anti-mushroom thread geometry, but worth noting if you’re used to standard bugle-head screws.

Finish and color

The white coating is even and reasonably tough. Running a driver bit slightly off center will scuff the paint on the head—par for the course with painted fasteners—but light scuffs blend into white fascia and railing. I didn’t experience flaking or chipping during installation. If you’re after a truly invisible look, these still benefit from a countersink and plug. Otherwise, the small, neat head reads as a clean, deliberate fastener in white trim.

Sizing considerations

These are 1-3/4 in. screws with a .195 in. shank—effectively a #10 by 1-3/4 in.—and they’re aimed at fascia, trim, and accessories rather than primary deck-board-to-joist fastening. For a typical composite fascia over 3/4 in. material into framing, 1-3/4 in. is a good match. If you’re fastening through thicker composite or into less substantial backing, consider stepping up in length in the same family to avoid the upper threads engaging before the tip has enough bite.

A quick rule that worked well for me:
- For fascia 1/2 to 3/4 in. thick into solid framing: 1-3/4 in. is appropriate.
- For deck boards or multi-layer trims: look for a longer version or pre-drill a clearance hole in the top layer.

Installation tips from the jobsite

• Use a T20 bit in good condition and keep it seated fully. Torx is forgiving, but dull bits still slip.
• Let the Type 17 tip do its work. Start slow, then increase speed once the tip bites.
• Near board ends or in cold weather, run a shallow countersink to avoid a raised rim and to help the head sit perfectly flush.
• If you feel the screw stall just as the head meets the surface, stop and back out one turn, then drive again at a slightly lower speed. If it repeats, create a clearance hole through the top material only.
• Set your clutch. Hardened steel screws are strong, but over-torqueing can deform the head or overheat the coating.
• Space fascia screws consistently; the small white heads look best in a clean grid.

Durability and holding power

The heat-treated steel and the dual-thread profile provide excellent hold. In both PVC and composite fascia, a gentle tug test after installation showed no movement or spin. I also appreciated that the threads didn’t chew up the entry hole, which helps keep the material tight to the substrate over time. The coating stood up to driver bit contact better than I expected; after a week of exposure, there was no sign of rust streaking around the heads.

Where these shine—and where they don’t

Strengths:
- Clean starts, low cam-out, and a finish that minimizes mushrooming when installed correctly.
- Color-matched white heads that blend into PVC and composite trim.
- A practical 1 lb box, so you’re not forced into contractor bulk for a single fascia job.
- ACQ compatibility and solid corrosion resistance for exterior use.

Limitations:
- The reversing threads can arrest forward travel if the screw is too short for the stackup or driven too aggressively; technique and sizing matter.
- If you expect the screw to countersink into every composite without any prep, you may be disappointed. Hard cap-stock still benefits from a light countersink pass for a perfect flush finish.
- Removal can be stubborn if the anti-mushroom threads are fully engaged in dense composite; plan your layout and test on scraps.

Value

For small to medium trim and fascia tasks, the quantity and feature set make sense. You get a purpose-built composite fastener with a reliable drive, anti-mushroom geometry, and corrosion protection without buying a 5 lb bucket. If you’re outfitting an entire deck surface, you’ll likely step up to larger quantities or a hidden fastener system; for fascia and accessory installs, this size and count are right on target.

Bottom line

I reached for these Jake Sales composite screws for fascia and trim work and got the clean, consistent results I wanted, with fewer raised rims and a tidy white finish. They reward proper sizing and a measured driving technique, and they hold tight in synthetic materials where general-purpose screws can struggle.

Recommendation: I recommend these for composite and PVC fascia, railing trim, and similar accessory fastening, especially if you want a white head that blends in. Choose the length carefully for your material stack, drive at a controlled speed, and don’t hesitate to run a light countersink on very hard cap-stock. If you need a fastener that will reliably disappear under a plug or sit cleanly flush in white trim, these are a solid pick.
