Professional Applications & Engineering Value
This aluminum split lock washer delivers critical vibration-dampening performance for industrial assemblies where weight reduction and corrosion resistance are paramount. The standard split lock design creates continuous spring tension against both bearing surface and fastener, effectively countering rotational loosening in machinery, electrical enclosures, and transportation equipment. Made from aluminum with Rockwell B87 hardness, it maintains optimal elastic recovery while eliminating galvanic corrosion concerns when paired with aluminum components. The precise 0.174" ID and 0.293" OD dimensions ensure proper seating on No. 8 screws, making it ideal for precision assemblies in aerospace, electronics, and lightweight structural applications where reliable vibration resistance cannot be compromised.
Specification Summary & Compliance
Manufactured to exact ASME B18.21.1 standard specifications for split lock washers, this No. 8 size washer features precise inch system dimensions (0.174" ID × 0.293" OD × 0.040" thickness) with standard Class 2A thread compatibility. The washer meets Rockwell B87 hardness requirements for consistent spring performance and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and global market acceptance for industrial fastener applications.
