Title:Bolts and Screws Roll Threaded Procurement Specification For
Issuing Committee:E-25 General Standards For Aerospace And Propulsion Systems
Scope:This procurement specification covers bolts and screws made from carbon steels, high expansion steels, or corrosion and heat resistant steels of the type identified under the Unified Numbering System as follows:a. UNS K00802 - carbon steel (AMS 5061)b. UNS K91505 - high expansion steel (AMS 5624)c. UNS K91456 - high expansion steel (AMS 5625)d. UNS S32100 - corrosion and heat resistant steel (AMS 5645)e. UNS S34700 - corrosion and heat resistant steel (AMS 5646)Product Code:SAE J737
Title:Hole Spacing for Scraper and Dozer Cutting Edges (Cancelled Aug 2007, Superseded by ISO 7129)
Issuing Committee:Mtc1, Loaders, Crawlers, Scrapers And Mounted Attachments
Scope:This standard is intended for cutting edge sections used on:a. Tractor-scrapers as described in SAE J1057 and J728b. Dozers as described in SAE J729. These cutting edges are further defined in SAE J738 for cross section and SAE J740 and J1580 for hole conformation. (Note: Some inch dimentions in this standard are not equivalent to the corresponding millimeter figures because values which are widely used have been adapted.This standard specifies hole placement along with length and width of the cutting edge.
