Does what a screw does
Not sure what to say really. It’s a wood screw. I had some wood and used a screwdriver and it screwed into the wood. I’d definitely buy these again if I have to screw something into wood.

Dont Screw About With Anything Else
The Spectre range has become by default brand and slowly change stock over to them.
Who would of thought you can save time, quick start thread bites into the wood cleanly.
Not had any wood split, super head design not had any round off.
Ideal for Impact screwdrivers too.

Best Screws I have used to date.
Superb screws, the best I have used to date, gradually replacing all my stock with these. Self cutting point, great screw head, never had one cam out, the driver bit wears out first! Excellent service from the ladies at Swadlincote branch click & collect service. Now my preferred branch and supplier ! You set the standards !
