Value Collection MP42458-16 M16 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION MP42458-16 is a metric split lock washer sized for M16 fasteners, manufactured from Grade 8 spring steel with a zinc plated finish. It features a 16.2 mm minimum inside diameter, a 27.4 mm maximum outside diameter, and a 3.5 mm thickness. The split lock design applies tension against the fastener and mating surface to resist loosening under vibration and dynamic loads. Hardness is rated at 44 to 51 HRC, consistent with Grade 8 spring steel requirements. This washer conforms to DIN 127 standards and is suitable for use in mechanical assemblies, structural connections, and equipment maintenance applications. Installation is handled by maintenance technicians, millwrights, and assemblers across industrial and commercial settings.

This washer is intended for use with M16 screws and bolts in metric fastener assemblies. Typical applications include machine frames, conveyor systems, pump and motor mounts, and general equipment fabrication where vibration resistance is required. The zinc plated finish provides a base level of corrosion resistance for indoor and light-duty outdoor use. Each unit is sold individually, with a minimum order quantity of 50 pieces per order.

Key Features

• Grade 8 spring steel construction with 44 to 51 HRC hardness for reliable locking force
• Zinc plated finish for basic corrosion protection
• Conforms to DIN 127 fastener standard
• 16.2 mm minimum ID to 17.0 mm maximum ID accommodates M16 fastener tolerance range
• 3.5 mm thickness provides consistent spring action under load
• Metric system of measurement for compatibility with DIN and ISO fastener systems

Compatibility

Designed for use with M16 metric screws and bolts. Conforms to DIN 127 and is suitable for metric fastener assemblies where a split lock washer is specified.

Installation Notes

Split lock washers are installed between the fastener head or nut and the mating surface before tightening. Ensure the fastener and mating threads are clean and free of debris before assembly. Do not reuse lock washers that have been fully compressed flat, as the spring action will not be restored. Installation should follow the torque specifications defined by the fastener manufacturer or applicable assembly standards.
