2 pcs Angle Plate Set — precision ground metal plates for accurate fixturing and inspection Key benefits Accurate, repeatable angles: Precision ground angles ensure consistent 45/45/90 and 30/60/90 references for setup, layout and inspection tasks. Stable, secure mounting: Four 11/32 inch holes and a 9/32 inch plate thickness provide rigid attachment to fixtures, tables or tooling plates so parts stay fixed during machining or inspection. Versatile use: Designed for installation in tools, production lines and inspection stations — useful for milling, drilling, layout, welding tack-ups and quality checks. What’s included Two angle plates: 45/45/90 plate: 3 inch x 3 inch x 4-3/8 inch 30/60/90 plate: 4 inch x 3-15/32 inch x 2 inch Material and construction Metal construction with precision ground angles for durability and accurate, long-term performance. Four mounting holes (11/32 inch diameter) for straightforward bolting or clamping. Plate thickness: 9/32 inch for stiffness and resistance to deflection under common fixturing loads. Practical applications Machining setup: Use the 45/45/90 plate to square workpieces in a milling machine or drill press for precise cuts and hole locations. Inspection and layout: Place parts against the precision-ground faces to verify angle accuracy or to mark reference lines before assembly. Fixture and welding support: Clamp workpieces to the 30/60/90 plate to hold nonstandard angles steady during tack welding or assembly operations. Why choose this set Provides two commonly used angle references in one compact, durable package. Simple mounting and standard hole size make the plates easy to integrate with existing tooling and tables. Precision ground surfaces reduce setup time and improve consistency between setups.
