WESTport involute spline plug gages check internal splined bores for composite (effective) error, tooth form, index/pitch, and effective/actual size. Supplied as GO and NO-GO sets: the GO member verifies full-form fit with the mating part, while the NO-GO guards individual space width.
Standards
Built to the major involute spline standards — ANSI B92.1, ANSI B92.2M, ISO 4156, DIN 5480, JIS B 1603, and SAE J498 — or to your drawing.
Actual and effective tolerance
Designed to both actual and effective tolerance, so a part that assembles correctly and stays within individual-feature limits is confirmed in one workflow.
Certification & quality
- Designed, ground, and hand lapped in-house for accuracy and long service life
- Certificate of Accuracy, NIST-traceable — included with every gage
- Calibrated in our ISO/IEC 17025 accredited laboratory; Long Form Certificate available on a 5–7 business day turnaround
