[4500 BULK] Hi-Collar Split Lock Washers Steel Plain 1/2

Hi-Collar Split Lock Washers are engineered to secure fasteners in demanding assemblies. Crafted from sturdy steel with a plain finish, these washers deliver reliable anti-loosening performance for 1/2" size hardware.

Designed for vibration-prone applications, the Hi-Collar profile creates a bite against the bolt and nut, increasing preload and helping prevent loosening under dynamic loads. The plain steel construction provides dependable strength for a wide range of non-corrosive environments.

• Material: Steel, plain finish (uncoated) for straightforward strength and compatibility.
• Size: 1/2" — intended for use with 1/2" fasteners (bolt/nut combinations).
• Type: Split lock washer with Hi-Collar geometry to improve seating and grip.
• Benefits: Reduces loosening from vibration, distributes load, and helps maintain clamping force.
• Applications: Ideal for machinery, automotive components, electrical enclosures, and general hardware assemblies where a reliable lock is required.

To install, place the washer under the bolt head or nut, tighten to specification, and ensure the split sits flat against the surface for optimal bite. For exposed or moisture-prone applications, consider a protective finish or plating if corrosion resistance is needed.
