Hillman 41240 Split Lock Washers 10mm 100-Pack Alloy Steel

Description

Product Overview

The Hillman 41240 split lock washers are crafted from high‑grade alloy steel that has been heat‑treated to achieve a hardened, matte finish. This material choice provides exceptional strength while resisting corrosion in harsh environments. Each washer measures 0.3937 inches in diameter, perfectly matching the M10 fastener size, and the split‑lock design creates a spring‑like tension that maintains a secure grip even under vibration. The flat, split head style ensures easy installation with standard tools, and the 100‑piece pack delivers enough inventory for large‑scale projects or repeated use in maintenance kits.

Designed for both industrial and consumer applications, these washers meet the specifications required for a wide range of machinery, automotive repairs, and construction assemblies. The hardened steel construction offers a durability rating that exceeds typical plain washers, reducing the need for frequent replacements. With a total weight of just 0.32 ounces per washer, the pack remains lightweight for convenient handling and storage.

Hillman, a trusted brand in fastener technology, guarantees that each washer conforms to strict quality standards. The product’s UPC 008236047578 and global trade identification number 00008236047578 provide traceability for inventory management. The split lock design is engineered to distribute load evenly, preventing loosening over time and extending the lifespan of the connected components.

Usage

These split lock washers excel in environments where vibration is a constant factor, such as automotive engines, industrial equipment, and heavy‑duty machinery. When paired with M10 bolts or screws, the washers act as a spring that absorbs shock, keeping joints tight and secure. They are also ideal for DIY enthusiasts tackling projects like furniture assembly, outdoor structures, or home improvement tasks that require reliable fastening.

Installation is straightforward: place the washer onto the threaded fastener before tightening the bolt or screw. The split portion of the washer flexes under tension, creating a locking action that resists back‑off. This makes the washers especially useful in applications where regular maintenance is required, as they reduce the frequency of re‑tightening.</n

Because the washers are made from hardened alloy steel, they can withstand exposure to chemicals, moisture, and temperature fluctuations without degrading. This resilience makes them suitable for outdoor installations, marine environments, and facilities with high humidity.

For professionals managing large inventories, the 100‑piece packaging simplifies ordering and reduces the need for multiple small shipments. The compact dimensions of the package (4.38 x 2.69 x 0.63 inches) allow for easy storage on shelves or in toolboxes.
