Value Collection 47416 M12 High Collar Split Lock Washer

Product Description

The VALUE COLLECTION 47416 is a metric high collar split lock washer designed for M12 fastener assemblies in mechanical and structural applications. Manufactured from Grade 2 steel with a bright uncoated finish, this washer conforms to DIN 7980 standards. It features a split design that bites into mating surfaces under load to resist loosening from vibration or torque. Inside diameter ranges from 12.2 to 12.7 mm, maximum outside diameter is 18 mm, and nominal thickness is 2.5 mm. The uncoated finish suits dry indoor environments or applications where a specific coating is applied after assembly. Electricians, pipefitters, millwrights, and maintenance mechanics commonly use this hardware in equipment mounting and conduit support work.

This washer is suited for metric M12 bolt and screw assemblies in light industrial, commercial, and mechanical installations. It is typically used between a fastener head or nut and the mating surface to maintain clamp load in bolted joints subject to vibration. The DIN 7980 standard designation makes it a recognized metric fastener component in European and internationally specified assemblies. Sold in multiples of 25 per order.

Key Features

• Conforms to DIN 7980 fastener standard for metric high collar split lock washers
• Grade 2 steel construction provides adequate strength for general-purpose bolted connections
• Inside diameter range of 12.2 to 12.7 mm fits standard M12 fasteners
• Nominal thickness of 2.5 mm delivers positive locking action under clamp load
• Bright uncoated finish — no coating buildup that could affect dimensional tolerance
• Metric system of measurement for compatibility with internationally specified hardware

Compatibility

Designed for use with M12 metric bolts and screws in assemblies requiring a high collar split lock washer per DIN 7980.

Installation Notes

Installation is performed by maintenance mechanics, electricians, or pipefitters as part of standard bolted joint assembly. Place the washer on the fastener shank with the split gap positioned so the collar faces the bearing surface before seating the nut or bolt head. Ensure mating surfaces are clean and free of debris to achieve proper clamp load. Always de-energize or lock out equipment per applicable safety procedures before performing fastener work on live machinery.
