Common rafter and hip/valley rafter scales permit one-number references for all cuts. The square is merely rotated to the proper roof pitch value on either scale to assure the correct angle cut. The slot along the scales will accommodate an adjustable locking pin for repetitive cuts using any 1/4-inch bolt and nut. Comes with a handy, 62 page pocket sized booklet that provides vital instructions, reference diagrams, and tables for the construction of roofs and stairs.

Will this tool benefit me more than the 7inch version?** A: I work as a carpenter and i have both the 7inch and a 12inch version.I carry The 7inch speed square with me all the time and use it a lot, the 12inch sqaure i keep in the toolbox because it's size makes it unpractical to carry with me and to be honest I rarly take it out and use it, maybe once or twice a month.So as for using at home I would go for the 7inch.If you occasionally need to make a longer marking then 7inch you can lay a straight board along the 90 degree side, then remove the square and make your marking. That works really well:)Hope this was useful for you!/Claes **Q: I just bought the 12" speed square, The slot that is supposed to hold the rise portion is way to large for the supplied 1/4" bolt? anyone else?** A: I just bought the same exact item from two different big box retailers. I bought and returned the first purchase because I assumed that the manufacturer had issued a recall on the item and the retailer had neglected to pull the existing stock from shelves. Because I was beginning a critical new stair job and I had chipped the pivot point on the 15 year old 12" speed square that I already owned, I bought another one from the second retailer. The product was defective from both retailers....and this is 10 months after your Sept. 2014 post.....apparently the problem has not been corrected by the manufacturer. **Q: β€œfirst time to buy and use the speed square. should i start off with 6in or the 12in? Beside their size, what other difference do they have”** A: I would suggest the 7" speed square. If you are going to be cutting a lot of 2x12's then the 12" would be handy in addition to the 7''. The 12" square comes with a layout bar for cutting stairs. ## Customer Reviews ### ⭐⭐⭐ Three Stars *by A***A on 25 October 2017* poor finish. ## Frequently Bought Together - Swanson Tool Co S0107 "Big 12" 12-Inch Speed Square Layout Tool with Blue Book - Swanson Tool Co S0100 Pro Carpenters Construction Aluminium Speed Square - Johnson Level & Tool 405 Stair/Square Gauge Set – 2/Card, Brass Plated, 2 Pack --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/156392123-swanson-tool-s0107-12-inch-speed-square-layout-tool-blue](https://www.desertcart.co.uk/products/156392123-swanson-tool-s0107-12-inch-speed-square-layout-tool-blue) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-19*
