Recommended SPAX Product: T-STAR plus Flat Head Yellow Zinc Multi-Material Construction Screws (Interior grade – the exact product designed for this kind of subfloor-to-hardwood repair) Why? Flat head – Drives completely flush (or slightly recessed) from the subfloor side. No pre-drilling needed in wood (thanks to the patented 4CUT point). Patented thread serrations give 40 % less driving torque and extremely strong pull-down force — this is what actually pulls the hardwood tight against the subfloor and stops the squeaking / popping. Best sizes for most homes (3/4" subfloor + 3/4" hardwood)- #8 × 2" (part # 4191020400504 – 1 lb box). #10 × 2-1/2" (part # 4191020500604 – 1 lb box) ← my top recommendation for maximum bite and holding power. These lengths give you full penetration through the subfloor plus ¾–1" into the hardwood — exactly what you need to lock the layers together without poking through the finished floor.
“Thanks for your question! “Brakes on metal” is a feature of our SPAX MULTI-head screws designed to protect metal fittings and ensure a perfect connection. Here’s how it works: • + Recessed segments for wood: When driving into wood, the recessed pockets mill away material for a clean, flush finish. • + Non-recessed “braking” surfaces for metal: As soon as the head contacts a metal fitting, the flat (non-recessed) portions engage and act like a brake. This stops the screw from over-tightening, prevents damage to the fitting’s surface, and still creates a rock-solid joint. In short, the “brakes on metal” feature automatically limits how deep the screw goes into metal, so you get consistent, secure fastening without stripping or distorting the part.”
Hello, Typically we suggest using a 2" minimum length fastener. Depending on your layers, it is recommended to have 1.25" penetration into the joist. - SPAX US
Hello, Yes that is a 1# box. Apologies that there is no larger box in our set for this product. SPAX US
Hello, the shear value of the #8 screw is 345 pounds. *Shear strength is determined in accordance with AISI S904 using minor thread diameter when fastener is tested in threaded section. Please also note, that is the value of the screw only, shear value of connection may be different based on wood or connector values. -SPAX US
