#8 x 2 Round Washer Head Truss Head Screw - Durable Exterior Wood

In this review of the #8 x 2 Round Washer Head Truss Head Screw the bottom line is simple: these screws are built for exterior and heavy woodworking tasks where corrosion resistance and reliable drive retention matter. For contractors, cabinetmakers, deck builders and serious DIYers, the biggest reason to buy is the combination of a modified truss washer head that delivers strong compression and a T-20 Torx drive that stays engaged during installation. The box of roughly 2000 screws also makes these a practical choice for larger projects where consistency and value are priorities.

Key Features

• Modified truss washer head: provides broad bearing area and strong compression for cabinets, siding and trim without sinking into softer materials.
• T-20 Torx drive: holds the bit firmly and reduces cam-out for quicker, more reliable installation with impact drivers.
• Black exterior coating: formulated for use with ACQ lumber and exterior projects to resist corrosion over time.
• V-shaped thread notches: cut board fibers at lower torque settings to reduce splitting when driving close to edges or into hardwoods.
• Salt spray tested: surviving 1,200 hours of salt spray testing without coating or screw failure for enhanced outdoor durability.
• Large pack size: approximately 16 lb box (~2000 screws) offers strong value for contractors and repeat users who need bulk fasteners.

Who It's For

These screws are ideal for professional carpenters, deck builders and serious DIYers working with exterior lumber, ACQ-treated wood, cabinets, furniture and trim where a durable, corrosion-resistant fastener is required. The large washer head is useful when a broader bearing surface is needed to prevent pull-through on softer stock.

Those who should look elsewhere include hobbyists needing only a handful of screws or situations requiring countersunk heads for concealed fastening; this product is a bulk, visible-head solution rather than a finish screw for invisible joins.

Pros & Cons

Pros

• Excellent corrosion resistance shown by 1,200 hours of salt spray testing, making these suitable for exterior use.
• T-20 Torx drive keeps the bit engaged, which customers note improves ease of installation and reduces breakage.
• Modified truss washer head offers strong compression and a larger bearing surface to prevent pull-through.
• V-shaped thread notches reduce splitting and make driving at lower torque settings more forgiving.

Cons

• The round washer head is exposed by design, so it is not ideal when a fully concealed, flush finish is required.
• Sold in a large bulk box, which may be more than casual users need at one time.
