Value Collection 361015PS M3.5 Split Lock Washer Grade 8

Product Description

The VALUE COLLECTION 361015PS is a metric split lock washer designed to resist fastener loosening under vibration and dynamic loads. Made from Grade 8 spring steel with a zinc plated finish, it delivers the tension and hardness required for reliable locking action in bolted assemblies. The washer measures 3.6 mm minimum inside diameter, 3.9 mm maximum inside diameter, 6.7 mm outside diameter, and 0.8 mm thick. Hardness is rated at 44 to 51 HRC. Manufactured to DIN 127 standards, this washer is installed by machinists, maintenance technicians, and assembly professionals working on metric fastener applications.

This split lock washer is suited for use with M3.5 screws in metric bolted assemblies across industrial, mechanical, and equipment maintenance applications. It is appropriate for both light-duty and general-purpose fastening scenarios where preventing fastener back-out is a priority. The zinc plated finish provides basic corrosion resistance for indoor and light-exposure environments. Sold individually per package, with a minimum order quantity of 100 pieces per order.

Key Features

• Grade 8 spring steel construction provides consistent preload and locking tension
• Hardness rated 44 to 51 HRC for reliable bite against mating surfaces
• Zinc plated finish for basic corrosion resistance
• Conforms to DIN 127 fastener standard
• Inside diameter range of 3.6 to 3.9 mm fits M3.5 screw shanks
• Metric system of measurement; does not meet military specifications

Compatibility

Designed for use with M3.5 metric screws and bolts in standard metric bolted assemblies conforming to DIN 127.

Installation Notes

Install between the fastener head or nut and the mating surface so the open ends of the split washer can bite into both surfaces as the fastener is torqued. Ensure the mating surfaces are clean and free of debris before assembly. Do not reuse split lock washers that have been fully flattened, as they will not provide adequate locking force. Follow applicable equipment or assembly specifications for fastener torque values.
