Holo Krome T436.1XRL-5 W/SLC Outside Micrometer 4-5" Carbide Ratchet Lock Nut

The T436.1XRL-5 W/SLC is a precision outside micrometer covering a 4" to 5" measurement range, designed for demanding inspection and quality control applications in machine shops and manufacturing environments. Equipped with carbide-tipped faces, a ratchet stop thimble, and a lock nut, this instrument delivers repeatable, accurate outside diameter measurements with a resolution of 0.0001" and vernier graduation for maximum reading precision.

Key Features:

• Measurement Range: 4" – 5" outside diameter
• Graduation: 0.0001" (vernier scale)
• Accuracy: ±0.00015"
• Carbide-tipped anvil and spindle faces for extended wear resistance
• Ratchet stop thimble ensures consistent, controlled measuring pressure
• Lock nut secures the spindle position for transfer measurements
• Tapered frame design allows access to narrow slots and recessed features
• Satin chrome finish reduces glare and resists corrosion
• Includes Standard Letter of Certification (W/SLC) traceable to NIST standards

The included Standard Letter of Certification (SLC) documents that this micrometer has been verified against known standards, making it suitable for regulated manufacturing, aerospace, and precision machining applications. The one-piece spindle construction and advanced sleeve design provide smooth, reliable operation throughout the instrument's service life.
