The JBO Thread Plug Gauge - BSW Go/No-Go - Right Hand - Medium Class - 3/8 x 16 is a precision inspection tool designed to verify internal threads quickly and reliably. Built for demanding environments in manufacturing, automotive, and aerospace, it helps ensure threaded holes meet standard BSW 3/8-16 right-hand specifications with consistent results.
With its go/no-go design, operators can perform fast pass/fail checks on hole threads—great for quality control, incoming inspection, or in-process testing—reducing guesswork and downtime while supporting accurate fitment across assemblies.
- Go/No-Go design for fast validation: Quickly determine whether a hole conforms to the 3/8-16 right-hand BSW thread, enabling immediate pass/fail decisions and smoother workflow on the shop floor.
- Precise 3/8 x 16 right-hand threading (BSW): Precisely machined ends ensure reliable checks against standard threads, helping prevent mismatches and failed assemblies.
- Rugged, knurled construction for everyday use: Solid metal body with a textured grip and accurately ground ends built to withstand daily handling in busy environments.
This plug gauge simplifies threaded-hole inspection, speeds up quality checks, and supports consistent, repeatable results across parts and operators. By providing an immediate gauge of conformity, it helps you reduce rework, select the correct fasteners faster, and maintain high-performance fitment in your manufacturing, maintenance, or repair workflows.
