Product features and benefits Precise, ready-to-use angle references: Each plate has precision-ground angles that provide accurate edge faces for layout, fixturing and inspection. Use them as dependable references when squaring, measuring or aligning workpieces. Durable metal construction: Made of metal with precision-ground faces for long-term stability and repeatable setup without frequent truing. Easy to mount and clamp: Each plate includes four 11/32 inch holes for secure attachment to fixtures, tables or jigs. Plates are 9/32 inch thick to resist flexing under clamping forces. What you get Two-piece angle plate set: 45/45/90 angle plate — size: 3 in x 3 in x 4-3/8 in 30/60/90 angle plate — size: 4 in x 3-15/32 in x 2 in Each plate is metal with precision-ground angles and four 11/32 in mounting holes. Why customers choose this set Versatile coverage: The 45/45/90 and 30/60/90 plates cover common angular setups used in machining, assembly and inspection, reducing the need for shims or temporary fixtures. Quick setups: Precision-ground surfaces allow fast, repeatable positioning of parts for milling, drilling, welding and inspection. Stability and repeatability: Adequate thickness and multiple mounting holes help maintain a rigid, secure reference under clamping and tooling loads. Typical applications Machine setup: Use the plates to square and hold parts on milling machines, drill presses or CNC fixtures for accurate hole placement and edge machining. Inspection and layout: Support workpieces at exact angles for go/no-go checks, layout scribing and dimensional inspection against precision faces. Welding and assembly jigs: Mount the plates to create stable right-angle and compound-angle supports for tack welding, assembly checks and repeatable production fixtures. Compatibility and use notes Mount using the four 11/32 in holes to attach to tooling plates, magnetic bases (if compatible), clamps or custom fixtures. The plates serve as reference surfaces; for critical tolerance work verify flatness and cleanliness before use. Supplied as a set of two specified angles (45/45/90 and 30/60/90) and exact sizes listed above.
