Value Collection P94160PS Hex Jam Nut M16 X 2 Grade 2H

Product Description

The VALUE COLLECTION P94160PS is an M16 x 2 hex jam nut manufactured from Grade 2H steel with a bright, uncoated finish. Jam nuts are thin-profile hex nuts used primarily as locknuts — threaded against a standard nut or a threaded rod to resist vibration-induced loosening. This nut measures 24 millimeters across the flats, 26.75 millimeters across the points, and 8 millimeters in height. It features a right-hand thread and meets the dimensional standards of DIN 439 and ISO 4035. At 0.01 pounds, it is lightweight and suited for high-volume fastener applications where space and stack height are critical.

This jam nut is used across industrial, structural, and mechanical assembly applications where a secondary locking nut is required. Typical scenarios include threaded rod assemblies, pipe hangers, machinery mounts, and any bolted joint subject to dynamic loads or vibration. It is appropriate for use by millwrights, pipefitters, ironworkers, electricians working with threaded rod strut systems, and general mechanical contractors.

Key Features

• M16 x 2 right-hand thread — standard metric coarse pitch
• Grade 2H steel construction for reliable tensile performance in locking applications
• Thin jam-nut profile at 8 millimeters height reduces stack height versus standard hex nuts
• 24 millimeters across flats — fits standard M16 wrenching tooling
• Bright, uncoated finish — suitable for dry indoor environments or secondary coating
• Conforms to DIN 439 and ISO 4035 dimensional standards

Compatibility

Designed for use with M16 x 2 metric coarse-thread fasteners and threaded rod in applications requiring a jam-nut locking configuration per DIN 439 and ISO 4035 standards.

Installation Notes

Installation is performed by threading the jam nut onto the fastener first, then threading the primary nut against it and tightening both in opposition using two wrenches — one to hold the jam nut and one to torque the primary nut. Power down or de-energize any associated equipment before working on fastened assemblies. Do not use impact tools to seat jam nuts, as over-torquing can strip the thin nut profile. Follow applicable structural or mechanical codes for the specific assembly type.
