Briggs & Stratton Hex Flange Nylon Lock Nut

Briggs & Stratton hex flange nylon lock nuts (also called nyloc nuts, nylon insert lock nuts or self-locking flange nuts) are genuine OEM fasteners for outdoor power equipment and small engines. Each nut has an external hex drive for standard wrench or socket installation. A built-in flange acts as an integrated washer. The nylon insert grips the threads to resist loosening.

Key Features:

• Nylon locking insert: Helps hold the nut in place under vibration and engine stress.
• Integrated hex flange: Spreads clamping load over a wider surface and removes the need for a separate washer.
• External hex drive: Works with common sockets and wrenches.
• Genuine OEM quality: Made to Briggs & Stratton factory specifications for use as a direct replacement on Briggs & Stratton engines and equipment.

Replacing worn or damaged lock nuts with genuine Briggs & Stratton hardware helps keep critical components secure. Nylon insert lock nuts are normally treated as single-use. Use a new nut whenever the fastener is removed.
