Combination Square — 12 inch

The Zeptix Supplies Combination Square is the single most versatile layout tool on a woodworker’s bench. The twelve-inch hardened steel blade slides through a precision-ground cast head and locks with a brass knurled nut that holds without slipping. Use the square face for 90-degree references, the 45-degree shoulder for miters, and the built-in spirit level for quick plumb and level checks. A hardened steel scriber stores inside the head, always ready for marking metal or scribing lines on end grain. The blade is etched with both imperial and metric graduations, and the satin finish reduces glare under shop lights so you can read fine divisions without squinting. The ground reference faces are accurate to within two-thousandths of an inch over the full blade length, which is more than sufficient for furniture-grade joinery. This is the kind of tool that repays its cost every time you set a table saw fence, check a miter joint, or mark a row of hinge mortises, and it will last decades with ordinary care.
