Measuring Roll Pins Set INSIZE 41 pcs (size range 1–5) model 4166-411

Set of 41 measuring roll pins from INSIZE, model 4166-411, providing a continuous range of pin sizes from 1 to 5. These precision roll pins are intended for accurate measurement, locating and fitting tasks in workshops, toolrooms and production environments. The set supports use in gauges, fixtures, inspection and assembly operations where consistent pin diameter and repeatable fit are required.

Advantages

The set offers a wide size range and close increments so users can select the exact pin diameter needed for fine measurement and fit verification. Manufactured to engineering tolerances appropriate for measuring tasks, the roll pins deliver consistent diameter, stable seating in jigs and reliable repeatability across repeated operations. The compact assortment reduces the need for single-piece purchases and simplifies task setup by keeping commonly used sizes together.

Suitable for

• Precision measurement and go/no‑go checking in inspection processes
• Locating and alignment of parts in fixtures and jigs
• Assembly operations requiring accurate dowel or pin fits
• Toolroom and maintenance tasks involving repeatable positioning
• Machining setups where temporary or permanent pinning is required

Key specifications

• Quantity: 41 pieces covering size range 1–5
• Type: measuring roll pins for precision locating and fitting
• Intended use: gauges, fixtures, inspection and assembly operations
• Construction: engineered for consistent diameter and repeatable fit
• Application environment: workshop, toolroom and industrial measurement

How to use

Select the roll pin with the diameter that corresponds to the required measurement or locating tolerance. Insert the pin into the gauge, fixture or workpiece hole until it seats securely; ensure the pin aligns with mating components and does not protrude or bind. For inspection tasks, use the roll pins to verify hole sizes, clearances and positional accuracy by comparing fit and feel against known references. When used in assembly or fixtures, confirm seating and retention to prevent movement during operation.

Usage recommendations

Store the pins in their original case or a labelled compartment to keep sizes organised and prevent surface damage. Inspect pins before use for burrs or deformation and replace any damaged items. Use appropriate insertion tools or soft-faced drivers to avoid altering pin diameter or surface finish during installation.
