L-Shaped Metal Bracket Detail Drawing with Threaded Fastener Locations

Technical Overview

This detailed engineering drawing depicts an L-shaped metal bracket (ESM0406A04051B) with precise mounting hole specifications and dimensions. This component features multiple threaded holes including 2×M3.8, 4×M3 (近直径), 3×C3, and 2×C3 fastening points strategically positioned throughout the design.

Key Dimensions:
– Overall dimensions approximately 211mm × 186mm
– Multiple critical mounting points at coordinates (0,0), (15,0), (65,0), etc.
– Precision-machined threaded holes with specific depth requirements
– Corner radius specifications of R5

The drawing includes multiple views (front, side, and isometric) showing the bracket’s 90-degree construction with flanges on both sides. Surface finish requirements are specified as Ra 6.3, indicating a medium-smooth surface texture suitable for mechanical applications. Tolerance specifications include multiple precision grades (u0.05, u0.1, u0.15, u0.2, u0.3) for critical dimensions.

This bracket appears designed for electronic equipment mounting or similar precision mechanical applications where exact positioning and secure fastening are required.
