Precision Angle Plate Set — Metal, Precision Ground Why you need this Provides accurate, rigid angle reference for machining, inspection, assembly, and layout tasks. Eliminates guesswork when setting up workpieces at common angles (45° and 30°/60°), improving setup speed and part accuracy. Pre-drilled mounting holes and solid metal construction make these plates easy to secure and durable in shop use. Key features Two-piece set: one 45/45/90 angle plate and one 30/60/90 angle plate. 45° plate size: 3 inch x 3 inch x 4-3/8 inch. 30° plate size: 4 inch x 3-15/32 inch x 2 inch. Four mounting holes per plate, each 11/32 inch diameter, for secure fastening. Plate thickness: 9/32 inch. Material: metal with precision ground angles for accurate, repeatable setups. Performance and compatibility Precision-ground angles provide true 45° and 30°/60° reference surfaces suitable for inspection and machining jigs. Mounting holes accept up to 11/32 inch diameter fasteners for stable clamping to fixtures, tables, or workpieces. Compact sizes fit into tight fixtures and workholding setups while providing solid support for small- to medium-sized parts. Typical applications Machining setups: Use the 45° or 30°/60° plates to square or angle parts on a milling machine, drill press, or surface plate. Quality inspection: Verify angles and alignment of produced parts against a precision reference during incoming inspection or in-process checks. Fabrication and assembly jigs: Build repeatable fixtures or use as stops and supports for welding, brazing, or assembly where accurate angles are required. What’s included Two angle plates (45/45/90 and 30/60/90) with four 11/32 inch holes each. Plate thickness 9/32 inch. Notes Angles are precision ground; handle and store plates to avoid dings that can affect accuracy. Fits fasteners up to 11/32 inch diameter for mounting.
