Decking Screws 10Gx50mm

These 10G x 50mm decking screws are SS304 stainless steel and come in boxes of 1000 per box. They’re sized to fix normal-thickness decking boards into joists, and the wide countersunk head sits flush, keeping the surface clean with no raised heads to catch a bare foot.

Sold in a 1000-piece box, so a bigger deck doesn’t mean stopping to buy more halfway through.

• SS304 stainless steel, so it resists rust and handles normal outdoor weather.
• 10 gauge (roughly 4.8mm) and 50mm long.
• Wide countersunk head that holds the board down and sits flush.
• T25 drive, with nibs under the head that stop the screw from slipping while you drive it.
• Type 17 point, which starts cleanly into the timber.
• Works in both softwood and hardwood.
• Through a 19mm to 22mm board, you get about 28mm to 31mm into the joist. Thicker boards leave less, so for boards thicker than 22mm or dense hardwood, check whether a longer screw such as 65mm is a better fit.

Application and Suitable Uses

• Softwood and hardwood decking – fixing boards down to joists
• Rails and fencing – outdoor timber where you want a rust-resistant screw
• Screening – privacy and feature screens
• General woodwork – outdoor timber jobs around the yard
• DIY projects – benches, planters and similar builds

Why Choose Decking Screws?

It all comes down to getting the fixing right for the timber. Stainless steel resists rust staining much better than plain steel. The wide head holds boards firmly and finishes flush, and 50mm is a good length for standard 19mm to 22mm boards with enough left over to grip the joist. A 1000-piece box covers a lot of deck.
