The PRECISION BRAND 17870 is a brass shim stock sheet used to fill gaps, align components, and set precise clearances in mechanical assemblies. Each sheet measures 0.01 inches thick, 18 inches long, and 6 inches wide, providing a workable blank that can be cut or trimmed to fit a wide range of applications. Brass is the material of choice when non-sparking, corrosion-resistant, or non-magnetic properties are required. This package includes 10 sheets. Machinists, millwrights, HVAC technicians, and maintenance professionals commonly use this stock during equipment installation, alignment, and preventive maintenance tasks.
Brass shim stock sheet is suited for residential and commercial mechanical work where tight tolerances are critical. Common applications include leveling and aligning HVAC equipment bases, setting bearing clearances, shimming pump and motor mounts, and fitting pipe supports. The 18-inch by 6-inch sheet size offers enough material to handle most standard shimming tasks without requiring further ordering of stock. The 0.01-inch thickness is a frequently specified gauge for moderate-clearance adjustments across a broad range of mechanical and HVAC installations.
Designed as a general-purpose brass shim stock sheet for use in mechanical, HVAC, plumbing, and industrial maintenance applications where a 0.01-inch thick brass sheet is specified.
Brass shim stock is typically installed by millwrights, HVAC technicians, or maintenance mechanics during equipment alignment and leveling procedures. Cut sheets to the required shape using metal shears, tin snips, or a utility knife on a stable work surface. De-energize and lock out all equipment before inserting shims into any mechanical assembly. Verify final clearance with a feeler gauge after shimming to confirm the target tolerance has been achieved.
