Accushim B-004 is a 3" x 3" stainless steel slotted shim, 0.004" thick, supplied in a box of 20 (PK/20). Made from 304 stainless steel, it features a central slot (approximately 25/32" wide) and a tab to aid placement, designed for precise height adjustments in machinery and alignment blocks. This replacement shim is intended for use with hold-down bolts in the 1/2" to 3/4" range, enabling repeatable, fine-tuned alignment in shaft assemblies and mounting applications. As part of the ACCUSHIM line of precut slotted shims, B-004 provides a consistent thickness option among multiple sizes to achieve exact leveling and alignment outcomes.
