S-92147A029 0.26" ID x 0.487" OD ASME B18.21.1 Split Lock Washers

Key Features & Benefits at a Glance

• Superior vibration resistance prevents fastener loosening in high-stress industrial environments
• Exceptional corrosion resistance with 316 stainless steel construction for harsh chemical and marine applications
• Reliable spring tension maintained through Rockwell C35 hardness for consistent locking performance
• Precision dimensional compatibility with 1/4" screws ensures perfect fit and optimal force distribution
• Industry-standard compliance with ASME B18.21.1 guarantees consistent quality and engineering reliability
• Environmental regulation adherence through RoHS 3 and REACH compliance for global manufacturing applications
• Durable split lock design provides continuous spring action that compensates for thermal expansion and material wear

Professional Applications & Engineering Value

These 316 stainless steel split lock washers deliver critical engineering solutions where vibration-induced fastener failure poses significant operational risks. The standard split lock design creates continuous outward pressure that counters rotational forces in machinery, automotive, and marine equipment. 316 stainless steel material offers superior protection against chloride-induced stress corrosion cracking, making these washers ideal for chemical processing, offshore platforms, and coastal installations. The Rockwell C35 hardness ensures the spring tension remains effective through repeated thermal cycles and mechanical stress. With precise 1/4" screw compatibility and ASME B18.21.1 compliance, these washers provide reliable performance in assembly lines, heavy equipment, and structural applications where maintenance access is limited and failure is not an option.
