Value Collection MS35338-155 Split Lock Washer No. 6 SS400

Product Description

The VALUE COLLECTION MS35338-155 is a No. 6 split lock washer manufactured from 400 series stainless steel with a passivated finish. Split lock washers function by biting into mating surfaces under load, resisting fastener back-off caused by vibration or thermal cycling. This washer meets military specification MS35338, making it suitable for applications requiring documented material and dimensional compliance. The inside diameter ranges from 0.141 to 0.148 inches, the maximum outside diameter is 0.25 inches, and nominal thickness is 0.031 inches. Licensed trades and maintenance technicians install these washers in assemblies where stainless corrosion resistance and vibration resistance are both required.

This split lock washer is suited for use with No. 6 fasteners in residential and commercial mechanical assemblies, enclosures, and equipment panels. The 400 series stainless steel construction handles moderate corrosion environments while retaining hardness appropriate for the locking function. The passivated finish removes surface contaminants and promotes a thin oxide layer that improves corrosion resistance without altering dimensions. Typical applications include HVAC equipment panels, electrical enclosures, plumbing support hardware, and general mechanical assemblies where a stainless No. 6 fastener is specified.

Key Features

• Meets military specification MS35338 for dimensional and material compliance
• 400 series stainless steel construction for corrosion resistance in moderate environments
• Passivated finish for improved surface corrosion resistance without dimensional change
• Inside diameter range of 0.141 to 0.148 inches fits No. 6 fasteners
• Maximum outside diameter of 0.25 inches for compact bearing surface
• Split helical design resists loosening under vibration and load cycling

Compatibility

Designed for use with No. 6 screws and fasteners in assemblies requiring a stainless steel split lock washer conforming to fastener standard MS35338.

Installation Notes

Installation requires no special tooling beyond standard hand or power drivers appropriate for the mating fastener. Ensure mating surfaces are clean and free of debris before seating the washer to allow full engagement of the locking edges. Do not reuse split lock washers that have been fully compressed flat, as the locking function is reduced. Follow applicable mechanical assembly codes and equipment manufacturer torque guidelines for the No. 6 fastener being used.
