Precision dial indicator insert with 0.001 inch resolution, designed as a directfit replacement for Smith and Wesson dial indicator gauge assemblies. Delivers consistent, repeatable measurements in a compact, durable package that is easy to install and use. Key benefits Accurate measurement: 0.001 inch resolution lets you detect and quantify very small variations, improving setup and inspection confidence. Direct compatibility: Designed to fit Smith and Wesson dial indicator gauge assemblies, making replacement or upgrade fast and hassle . Durable construction: Metal housing and stem provide reliable service in and field environments, resisting wear from regular use. Simple installation and use: Compact form factor and standard mounting dimensions allow straightforward mounting in existing indicator posts and fixtures. Stable, repeatable readings: Low play and solid contact design reduce reading variability for consistent results across multiple checks. Important attributes Function: Precision displacement measurement for alignment, runout, position checking, and tolerance verification. Compatibility: Replacement insert for Smith and Wesson dial indicator gauge units and other indicators that accept the same insert dimensions. Resolution: 0.001 inch increment readings for fine measurement tasks. Size and fit: Compact insert format sized for standard indicator housings and mounts used with Smith and Wesson gauge assemblies. Material and finish: Robust metal construction built for repeated contact and operational durability. Performance: Designed to provide stable pointer movement, quick response, and repeatable readings under normal conditions. Practical applications Gunsmithing and firearm maintenance: Check small alignment shifts, verify fit and movement of small components, and inspect dimensional changes after or modification. Workshop setup and machining: Use during lathe or mill setups to align work, check runout on bores or shafts, and confirm minimal tolerances before finishing operations. Quality control and part inspection: Inspect small parts, gauges, and assemblies for dimensional consistency and to document pass fail status during production or . What to expect A precision measurement insert intended to restore or upgrade the functionality of compatible dial indicator gauge assemblies. Straightforward replacement using standard indicator mounts, providing accurate 0.001 inch readings without extensive recalibration. Compatibility note Intended for use with Smith and Wesson dial indicator gauge models and other indicators that accept the same insert dimensions. Confirm fit with your specific gauge before .
