Key features and benefits - mounting versatility: four mounting holes 11/32 inch diameter ensure secure attachment to tools, jigs, and fixtures; plate thickness is 9/32 inch for a stable, rigid base - precise alignment: each plate has precisely ground angles to promote accurate setup and reproducible results in tooling, production, and inspection - durable construction: made from metal with precision ground angles to maintain accuracy under typical shop conditions - versatile two piece set: includes two angle plates with different angle configurations for flexible workholding and alignment Included items and specifications - 2 piece angle plate set - 45/45/90 degree plate: size 3 x 3 x 4-3/8 - 30/60/90 degree plate: size 4 x 3-15/32 x 2 - mounting holes: four holes, each 11/32 inch diameter - plate thickness: 9/32 inch - material: metal with precision ground angles Why you need this and how it helps - improves setup time: precise ground angles allow quick, repeatable positioning of workpieces - enhances accuracy: stable, square references reduce errors during machining, drilling, and inspection - broad compatibility: suitable for tools, production lines, and inspection fixtures that require reliable angle references Practical use scenarios - milling and drilling setup: use the 45/45/90 plate to establish a square reference with a workpiece mounted securely on a machine table - inspection fixtures: employ the 30/60/90 plate to align parts in inspection jigs for accurate angle checks and measurements - jig and fixture construction: combine both plates to create reliable angle references for assembling components or testing tolerances in a production line Note: All dimensions are provided to maintain alignment with standard workholding practices. The two plates offer complementary angles to support a variety of mounting and alignment tasks in tool, production, and inspection environments.
