Frequently Asked Questions
Q: What are the dimensions of the 787398 M8 flat washer?
A: The 787398 has an inner diameter of 8.4 mm, outer diameter of 16 mm, and thickness of 1.6 mm. These dimensions ensure proper load distribution under M8 bolt assemblies in electric lift truck applications.
Q: What material is the 787398 washer made from?
A: The 787398 is constructed from Grade 8 carbon steel with an oil finish and phosphate coating. Grade 8 provides a Rockwell hardness of C38 to C45, delivering superior strength and corrosion resistance compared to lower grades.
Q: Will the 787398 work with M8 bolts across different lift truck brands?
A: Yes. The 787398 is a standard metric M8 washer and will fit any M8 bolt assembly used in electric lift trucks from Crown, Toyota, Raymond, Yale, Hyster, and other major OEMs. Verify bolt specifications match before ordering.
Q: How long does the 787398 washer last?
A: Grade 8 carbon steel with phosphate and oil finish provides extended service life in standard indoor and outdoor material handling environments. The washer does not wear out but may require replacement if corrosion penetrates the protective finish or if the bolt assembly is removed and reused multiple times.
Q: Is the 787398 suitable for wet or cold storage applications?
A: The phosphate coating and oil finish provide moderate corrosion resistance. For prolonged exposure to wet floors or cold storage, Grade 8 carbon steel washers are adequate but should be inspected regularly for rust breakthrough. Consider stainless steel alternatives for high-corrosion environments.
