Description
Product Overview
The uxcell 5/16 Internal Tooth Lock Washer set delivers premium performance for demanding fastening applications. Each pack contains 40 washers crafted from 304 stainless steel, a material celebrated for its high hardness, excellent corrosion resistance, and long‑term durability. The star‑shaped internal tooth design generates a consistent spring force that locks the fastener head firmly against the base material, preventing loosening caused by vibration, thermal expansion, or dynamic loads. With an inner diameter of 8 mm (0.31 in) and an outer diameter of 15.3 mm (0.6 in), the washers fit a wide range of bolt sizes while maintaining a low profile of just 0.8 mm (0.03 in) thickness. The smooth, burr‑free surface ensures easy insertion and removal, making these washers ideal for both new assemblies and maintenance repairs.
Usage
Designed for versatility, these internal tooth lock washers excel in automotive, marine, and industrial environments where reliable joint integrity is critical. Whether securing engine brackets, mounting marine hardware, or reinforcing equipment housings, the washers provide a vibration‑resistant lock that reduces the risk of fastener fatigue. Their stainless‑steel construction makes them suitable for exposure to saltwater, chemicals, and high‑temperature conditions, ensuring consistent performance in harsh settings. Installers appreciate the straightforward application: simply place the washer onto the bolt shaft, tighten the nut, and the internal teeth will bite into the fastener head, creating a secure, non‑slipping connection.

FAQ
What size bolt can these washers accommodate?
The washers have an 8 mm (0.31 in) inner diameter, making them compatible with bolt shank sizes up to M8 (approximately 0.315 in) and similar metric or imperial dimensions.
Are the washers reusable after removal?
Yes, the stainless‑steel construction and robust tooth geometry allow the washers to be removed and reinstalled multiple times without significant loss of locking performance.
Can these washers be used in high‑temperature environments?
304 stainless steel maintains its mechanical properties up to about 870 °C (1600 °F), so the washers are suitable for most high‑temperature applications encountered in automotive and industrial settings.
Do the washers require any special tools for installation?
No special tools are needed. Standard wrenches or socket sets are sufficient to tighten the nut and engage the internal teeth.
What is the difference between an internal tooth lock washer and a regular lock washer?
Internal tooth lock washers feature teeth on the inner surface that bite into the fastener head, providing a more secure lock compared to external teeth that grip the nut or bolt thread. This design offers superior resistance to vibration and torque loss.
