Shim Washer - 1.0 OD x 5/8 ID x .040

The T AND D MACHINE Shim Washer – 1.0 OD x 5/8 ID x .040 (SKU: TDM0660-040) is a precision flat washer engineered for critical spacing and alignment applications where exact tolerances are essential. This steel shim washer measures 1 inch outer diameter with a 5/8 inch inner diameter and 0.040 inch thickness, making it ideal for machinery assembly, firearm component stacking, equipment calibration, and structural alignment where gap correction and load distribution are required.

Manufactured from durable steel, this shim washer provides consistent thickness and flatness for reliable performance in high-tolerance builds. The 0.040 inch thickness is a common specification in precision engineering, offering sufficient material for strength while maintaining the minimal profile needed in space-constrained applications. The 5/8 inch bore accommodates standard fastener sizes, while the 1 inch outer diameter distributes clamping force across a broader surface area, reducing stress concentration on mated components. Whether shimming barrel extensions, adjusting headspace on precision builds, or correcting minor misalignment in mechanical assemblies, this washer maintains dimensional accuracy across repeated assembly and disassembly cycles.

Precision shooters, gunsmiths, and equipment manufacturers rely on individual shim washers to fine-tune critical clearances without compromising structural integrity. The modest weight (0.01 lbs) ensures that stacking multiple units for greater total thickness adds negligible mass to assemblies. Sold as a single unit, this washer serves as a reliable stock component for inventory or as part of larger shimming kits for custom builds requiring exact gap specification.
