Value Collection SIWIX0-6USA-100BX Lock Washer 6 Screw

Product Description

The VALUE COLLECTION SIWIX0-6USA-100BX is a 6 screw internal tooth lock washer manufactured from grade 18-8 stainless steel. Designed to resist loosening caused by vibration and torque, internal tooth lock washers grip the mating surface through multiple inward-facing teeth that bite into both the fastener bearing surface and the workpiece. With an inside diameter of 0.15 inches, an outside diameter of 0.288 inches, and a thickness of 0.017 inches, this washer seats flush under standard number 6 fastener heads. The uncoated 18-8 stainless steel construction provides corrosion resistance suitable for wet, outdoor, and chemically exposed environments. This box contains 100 washers per order.

Internal tooth lock washers in this size range are widely used in HVAC equipment assembly, electrical panel and junction box installations, plumbing fixture mounting, and general mechanical assemblies where a number 6 machine screw or sheet metal screw is the fastener of choice. They are commonly installed by HVAC technicians, electricians, and plumbers during equipment fabrication, panel work, or field repair where vibration-resistant fastening is required on stainless or dissimilar metal surfaces.

Key Features

Compatibility

Designed for use with number 6 machine screws and sheet metal screws requiring an internal tooth lock washer with a 0.15 inch inside diameter and 0.288 inch outside diameter.

Installation Notes

Internal tooth lock washers are installed between the fastener head and the mating surface before the fastener is driven. Ensure the mating surface is clean and free of debris so the teeth seat properly. Do not reuse lock washers once a fastener has been fully torqued, as the teeth may be deformed. Power down or de-energize any electrical assembly before installing or replacing hardware in live panels.
