Hyjoy #9 1-1/2" Connector Screws for Joist Hangers — 1/4" Shank with 0.37" Washer, Pre-Galvanized Corrosion-Resistant, Replaces 9112R500 and 10D

Replacement connector screws #9 x 1-1/2" designed for joist hangers and compatible with All-Drive connector systems. These screws replace 9112R500 and standard 10D nails and include a driver for easy installation. The 1/4" shank is fitted with an integrated 0.37" diameter washer and each screw may be used independently of a connector when required. Durable multi-layer RUSPERT finish — applied by a thermal process — provides superior corrosion protection. The coating combines a dense ceramic outer surface, a polymer chemical bonding layer to resist peeling, and a zinc-rich primer for cathodic protection. This treatment outperforms conventional mechanical galvanization and has passed a 480-hour salt spray test, making the screws suitable for acidic, humid, coastal, and sulfide-corrosive atmospheres. Built from high-strength material and optimized during manufacturing, each #9 1-1/2" screw delivers a single-screw load capacity that significantly exceeds that of a standard 10D nail. Use them with confidence in decks, framing, joist hangers, fences, bridges, and other indoor or outdoor projects where superior shear and withdrawal performance is needed.
