Briggs & Stratton 8165001 Hex Flange Nylon Lock Nut - 1/4-20

The Briggs & Stratton 8165001 is a 1/4-20 hex flange nylon lock nut with zinc plating for corrosion resistance. This fastener combines the benefits of a hex flange nut with a nylon insert locking mechanism, providing both a wider bearing surface and resistance to vibration loosening.

Key Features:

• 1/4-20 thread size for standard fractional applications
• Hex flange design provides increased bearing surface and eliminates need for separate washer
• Nylon insert lock nut design resists loosening from vibration
• Zinc plated finish offers corrosion protection
• Genuine Briggs & Stratton OEM replacement part

This flange lock nut is commonly used in small engine applications, outdoor power equipment, and general mechanical assemblies where a secure, vibration-resistant fastening solution is required. The integrated flange distributes clamping load over a larger area compared to standard hex nuts.
