fixture locating pins
Product Overview
Fixture locating pins are precision components used in industrial manufacturing to accurately register workpieces and clamp sets so each part is produced in the same position. In metalworking and machining environments—where repeatability, setup efficiency, and dimensional stability matter—fixture locating pins help establish a reliable datum between the fixture and the workpiece. When the locating interfaces are consistent, operators can reduce rework, improve first-pass yield, and streamline changeovers across production runs.
Key Features
- Repeatable alignment: Designed to consistently position the fixture relative to the workpiece, supporting stable machining results.
- Faster setups: Positive location reduces time spent dialing in fixtures during tool changes, model switches, or maintenance.
- Improved interchangeability: Helps ensure that fixtures, pallets, and clamping assemblies can be swapped with minimal recalibration.
- Reduced wear on locating surfaces: Helps maintain the accuracy of the mounting interfaces by improving how load is transferred.
- Cleaner process control: Reliable datum positioning supports consistent measurement points for inspection and SPC.
- Robust for shop-floor use: Suitable for recurring setups where fixtures experience repeated handling and clamp cycles.
- Compatible with common fixture systems: Works with typical drilled or reamed locating holes used in jigs, pallets, and machining fixtures.

Application Scenarios
- Machining repeatability: Locates the workpiece during milling or drilling to maintain consistent tool engagement and part geometry.
- Pallet-based production: Enables quick fixture changes while keeping the same datum reference across multiple clamps and shifts.
- Assembly alignment: Registers components during alignment steps to reduce misfit between mating parts and subassemblies.
- Rework reduction: Improves consistency when returning parts to a station after inspection or corrective operations.
- Fixture refurbishment: Supports replacement of worn locating elements so older tooling can regain close-to-original positional accuracy.
Advantages
Compared with generic dowel pins or off-the-shelf positioning pieces, this locating pin approach is built around fixture performance goals: consistent registration, stable datum control, and reduced setup variation. When your fixtures depend on repeatable location, the right pin geometry and fit strategy helps minimize play, reduces the cumulative effect of wear on mating holes, and supports predictable inspection results.
The outcome is fewer process interruptions and tighter control of part placement across production lots—especially valuable for jobs that involve frequent changeovers, multi-station routing, or pallet-based workholding.

FAQ
Q: What are fixture locating pins used for in manufacturing?
A: They provide precise datum registration between a workpiece and a jig, pallet, or machining fixture to improve repeatability and reduce setup variation.
Q: How do I choose the correct pin size and fit?
A: Select pin diameter and length based on your existing locating hole condition (e.g., drilled/reamed) and the level of positional control required for your process.
Q: Can these pins be used for different fixture designs?
A: Yes, when the mating hole system and installation method are compatible; otherwise, they may require adjustment to maintain the intended location accuracy.
Q: Do I need to replace them during fixture refurbishment?
A: Many refurbishment programs replace worn locating elements to restore consistent positioning and reduce the tolerance drift caused by repeated clamp cycles.
Q: What information should I provide for a quotation?
A: Share your required quantity, pin dimensions/lengths (or a drawing), the mating hole specification, and the application (machining, assembly, pallet system) so we can confirm the best configuration for your fixture layout.
