Professional Applications & Engineering Value
This aluminum split lock washer delivers exceptional engineering value in applications where vibration-induced loosening poses significant reliability concerns. The standard split lock design creates continuous spring tension that compensates for material relaxation and thermal cycling, making it ideal for electrical enclosures, aerospace components, and precision machinery using No. 10 screws. The aluminum material offers natural corrosion resistance without requiring additional coatings, while maintaining Rockwell B87 hardness ensures the washer maintains its locking capability through repeated compression cycles. These industrial lock washers are particularly valuable in weight-sensitive applications where steel alternatives would add unnecessary mass while providing equivalent vibration resistance.
