Emuge L0100100.5623 Plug Thread Gage 5/8-11 Sti 2B

Product Description

The EMUGE L0100100.5623 is a double-end plug thread gage designed to inspect 5/8-11 STI (Screw Thread Insert) threads to ASME B1.2 standards. One end carries the Go member; the opposite end carries the No Go member, allowing a technician to verify both minimum and maximum thread tolerance in a single tool. The gage is manufactured from tool steel with a bright, uncoated finish and conforms to Class 2B tolerance classification. A short-form certification is included. This tool is used by machinists, quality inspectors, and maintenance technicians who need to verify STI thread inserts before assembly.

STI thread gages are used wherever Heli-Coil or equivalent wire thread inserts are installed into tapped holes. Common applications include aerospace component repair, engine block thread restoration, and precision machined parts where an insert restores or reinforces a threaded bore to accept a standard fastener. The 5/8-11 size is a coarse-thread designation frequently encountered in structural fastener applications. This gage is suited for shop floor inspection, incoming quality control, and field verification of repaired threads in heavy-duty assemblies.

Key Features

• Double-end design combines Go and No Go members in one gage body
• Inspects 5/8-11 STI threads to ASME B1.2 standard
• Tool steel construction for wear resistance and dimensional stability
• Bright, uncoated finish preserves gauge diameter integrity
• Right-hand thread direction
• Short-form certification included for documentation and traceability

Compatibility

Designed to inspect 5/8-11 STI internal threads conforming to Class 2B tolerance per ASME B1.2. Applicable wherever wire thread inserts of this size and thread form are used.

Installation Notes

Thread plug gages are used by quality control technicians and machinists, not installed permanently. Before gaging, clean the threaded bore of chips, oil, and debris to avoid false readings. Apply the Go member hand-tight only - never force it with tools, as this can damage the gage or the part. Store the gage in its case away from other tooling to protect the precision-ground thread members.
