Key Features & Benefits at a Glance

  • Superior corrosion resistance from brass construction, ideal for humid or chemically aggressive environments
  • Exceptional durability with Rockwell B60 hardness, maintaining structural integrity under heavy loads
  • Precision dimensional control ensures perfect fit for 5/16" screws with 0.34" ID and 0.75" OD specifications
  • Reliable load distribution through controlled 0.052-0.072" thickness range, preventing surface damage
  • Environmental compliance assurance with RoHS 3 and REACH standards for global industrial applications
  • Reduced maintenance requirements due to brass's natural anti-galling and non-sparking properties
  • Long-term cost efficiency through extended service life in demanding mechanical assemblies

Professional Applications & Engineering Value

Engineered for demanding industrial environments, these brass flat washers provide critical solutions where corrosion resistance and electrical conductivity are paramount. The Rockwell B60 hardness ensures consistent performance in high-vibration applications while preventing embedding in softer materials. Perfect for 5/16" screw size assemblies in marine equipment, electrical panels, and plumbing systems, the precise 0.34" ID and 0.75" OD dimensions guarantee optimal load distribution without bolt hole interference. The inch system measurement compatibility makes them ideal for North American machinery maintenance and OEM applications requiring reliable flat washer performance under continuous operational stress.

Specification Summary & Compliance

Manufactured to precise dimensional standards with 0.34" inner diameter and 0.75" outer diameter specifications, maintaining consistent 0.052-0.072" thickness tolerance. Complies with industry-standard inch measurement systems for 5/16" screw size applications. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in global industrial markets. Material certification includes Rockwell B60 hardness verification for consistent mechanical performance across production batches.
