Value Collection 630-4302 Angle Block 2 Degree 55 Hrc

Product Description

The VALUE COLLECTION 630-4302 is a hardened steel angle block used in precision layout, inspection, and machining setups. The block holds a fixed 2-degree angle on both faces and measures 3 inches in overall length. At 55 HRC hardness, the contact surfaces resist wear and maintain accuracy over repeated use. An accuracy rating of 20 arc-seconds makes this block suitable for toolroom work, sine plate setups, and fixture building where repeatable angular reference is required. Machinists, tool-and-die makers, and quality technicians typically keep angle blocks as part of a standard precision measurement kit.

This angle block is suited for use on surface plates, magnetic chucks, and milling fixtures where a precise 2-degree offset is needed. It supports workholding, part inspection, and angular transfer tasks in machine shops, toolrooms, and quality control environments. The 3-inch length provides a usable reference surface for small to medium workpieces. The block ships individually and is appropriate for both production and jobsite inspection use.

Key Features

• Fixed 2-degree angle on both faces for repeatable angular reference
• 55 HRC hardness resists wear on contact and reference surfaces
• 20 arc-second accuracy rating suitable for toolroom-grade inspection
• 3-inch overall length provides adequate reference surface for most setups
• Compact and lightweight at 0.2 pounds for easy handling and storage

Compatibility

Designed as a standard angle block for use with surface plates, sine bars, magnetic chucks, and precision fixtures requiring a fixed 2-degree angular reference in toolroom and machining applications.

Installation Notes

Angle blocks are used by machinists and quality technicians and require no permanent installation. Clean the reference surface and the block contact faces before use to remove chips, burrs, or oil film that could affect accuracy. Handle with care to avoid impacts that may alter hardness or surface geometry. Store in a protective case or on a clean surface away from abrasive materials.
