RS PRO Blue Polyester Plastic Shim 457 mm x 305 mm x 0.05 mm 770-737

RS PRO 770-737 Blue Polyester Plastic Shim is a high-quality alignment and spacing component suited for a wide range of engineering, mechanical, and industrial applications. Featuring a robust polyester construction, these shims offer superior resistance to corrosion and weathering, making them ideal for challenging environments where metal shims may deteriorate.

The shim measures 457 mm in length, 305 mm in width, and 0.05 mm in thickness. This precise sizing makes it suitable for fine adjustments, calibration, and sealing tasks where exact spacing is critical. The blue colour coding enhances identification, especially when multiple shims are used for layered operations or bundled assemblies.

Plastic Shims play an important role not only in achieving accurate alignment but also as protective barriers to prevent galvanic corrosion between dissimilar metals. The polyester material ensures electrical insulation, reduces wear, and contributes to long service life. This product comes as a convenient pack of eight sheets, supporting both new installations and ongoing maintenance requirements.

Common industrial applications include use in machinery alignment, structural assembly, fluid power systems, HVAC installations, laboratory equipment calibration, and manufacturing process adjustments. The thin 0.05 mm profile is particularly advantageous for incremental adjustments without adding significant mass or altering system configuration.

Manufactured in the United Kingdom, RS PRO shims comply with strict industrial standards. They are a reliable solution for engineers, maintenance professionals, and facility managers seeking versatile, easy-to-use alignment materials for industrial, laboratory, and commercial environments.
