uxcell 100Pcs 6# Internal Tooth Lock Washer 304 Stainless Steel Star

Description

Product Overview

The uxcell 100Pcs 6# Internal Tooth Lock Washer is engineered from premium 304 stainless steel, a material renowned for its high hardness, excellent corrosion resistance, and long‑term durability. Each washer features a precision‑cut internal tooth star design that provides a reliable spring‑loaded locking action, ensuring that fasteners remain securely tightened even in high‑vibration environments. The washers measure 3.7 mm (0.15 in) inner diameter, 7.3 mm (0.29 in) outer diameter, and 0.5 mm (0.02 in) thickness, making them compatible with a wide range of bolts, screws, and nuts commonly used in automotive, marine, and industrial applications.

Manufactured with meticulous attention to detail, the washers exhibit a smooth, burr‑free surface that facilitates easy installation and removal without damaging mating components. The 304 stainless steel composition also offers superior resistance to rust and chemical exposure, extending the service life of the fastener assembly. The star‑shaped internal teeth engage directly with the fastener head, creating a consistent clamping force that mitigates the risk of loosening caused by thermal expansion, shock loads, or continuous vibration.

Designed for reusability, these lock washers can be installed and removed multiple times without loss of performance, providing cost‑effective reliability for maintenance‑intensive projects. The package includes 100 pieces, neatly organized in a compact box measuring 3.54 × 2.32 × 0.67 in, weighing only 0.71 oz, which simplifies inventory management and on‑site handling. Whether you are assembling a high‑performance engine, securing a marine pump, or constructing a robust industrial framework, these washers deliver the precision and strength required for demanding applications.

Usage

These internal tooth lock washers excel in environments where vibration and dynamic loads are prevalent. In automotive assemblies, they are ideal for securing engine brackets, transmission mounts, and suspension components, where maintaining torque is critical for safety and performance. Marine applications benefit from the stainless steel’s resistance to saltwater corrosion, making the washers suitable for boat hull fittings, propeller shafts, and deck hardware that are constantly exposed to harsh marine conditions.

Industrial settings such as manufacturing equipment, heavy machinery, and power generation systems also rely on the consistent locking capability of these washers. They are frequently used in electrical enclosures, HVAC units, and conveyor systems to prevent loosening of bolts that could lead to equipment downtime or safety hazards. The washers’ compact size allows them to be employed in tight spaces where traditional lock washers might not fit, providing a versatile solution for a broad spectrum of fastening challenges.

Installation is straightforward: simply place the washer onto the bolt or screw, align the internal teeth with the fastener head, and tighten the nut to the specified torque. The spring‑loaded action of the star design automatically compensates for minor variations in torque, ensuring a uniform clamping force across the assembly. This ease of use reduces installation time and minimizes the need for specialized tools, making the washers a practical choice for both professional technicians and DIY enthusiasts.

FAQ

What size fasteners are compatible with these lock washers?

The washers have an inner diameter of 3.7 mm (0.15 in) and an outer diameter of 7.3 mm (0.29 in), making them suitable for bolts and screws ranging from M3 to M4, as well as standard #6 to #8 hardware commonly used in automotive and marine applications.

Can these washers be used in high‑temperature environments?

Yes. The 304 stainless steel material retains its mechanical properties at elevated temperatures up to approximately 870 °C (1600 °F), allowing the washers to function reliably in heat‑intensive settings such as engine compartments and industrial furnaces.

Are the washers reusable after removal?

Absolutely. The precision‑cut internal teeth and robust stainless steel composition enable the washers to be installed and removed multiple times without loss of locking performance, making them a cost‑effective choice for maintenance‑heavy applications.

How do these washers compare to traditional split lock washers?

Unlike split lock washers that rely on spring tension alone, the internal tooth star design engages directly with the fastener head, delivering a more consistent and higher locking torque. This results in superior resistance to vibration‑induced loosening and a longer service life.

What is the recommended torque setting for installation?

While torque values can vary based on the specific fastener and application, a general guideline is to tighten the nut to the manufacturer’s recommended torque for the bolt size, typically between 5 Nm and 10 Nm for M3‑M4 fasteners. The star washer’s spring‑loaded action will automatically adjust to maintain proper clamping force.

These comprehensive details ensure that the uxcell 100Pcs 6# Internal Tooth Lock Washer meets the rigorous demands of professional engineers, technicians, and hobbyists alike, delivering dependable performance across a multitude of applications.
