Value Collection 418-4220 Right Angle Iron 1 Hole

Product Description

The VALUE COLLECTION 418-4220 is a right angle iron used to establish precise 90-degree reference planes in machining, inspection, and layout work. Constructed from semi-steel with a precision-ground finish, this angle iron holds parallel and square tolerances within 0.0018 inches per 6 inches. It measures 8 inches high, 4-1/2 inches wide, and 5 inches deep, with a single hole for fixturing or clamping. At 21 pounds, it provides the mass and stability needed for accurate setup work on surface plates, mill tables, and inspection benches. Machinists, tool-and-die makers, and precision inspectors rely on this type of tooling for squaring workpieces and checking perpendicularity.

This angle iron is suited for use in precision machining shops, fabrication facilities, and quality control environments. Its semi-steel construction and ground surfaces make it appropriate for both production fixturing and one-off inspection setups. The single-hole configuration supports clamping or mounting to tables and fixtures. This unit ships individually and is sold as a single piece.

Key Features

• Precision-ground finish maintains square and parallel tolerance within 0.0018 inches per 6 inches
• Semi-steel construction provides rigidity and mass for stable setups
• Single hole supports clamping, fixturing, or mounting applications
• 8 inches high by 4-1/2 inches wide by 5 inches deep for substantial reference surface area
• 21-pound mass minimizes movement during workpiece setup or inspection

Compatibility

Designed as a general-purpose right angle iron for use on surface plates, mill tables, and inspection fixtures in standard machining and metrology applications.

Installation Notes

Right angle irons are typically positioned and clamped by machinists or metrology technicians on a clean, flat reference surface such as a granite surface plate or machine table. Always clean mating surfaces before placing the angle iron to avoid rocking caused by chips or debris. Secure any workpieces or clamps according to your shop fixturing standards before applying cutting forces or measurement loads. Inspect ground surfaces periodically for nicks or corrosion that could affect squareness accuracy.
