Carbon Steel Bolt With Slotted Hex Head Bolt and Partially Threaded Shank

Railway and transportation equipment builders sourcing a slotted hex head carbon steel bolt require thread major diameter and slot width to verify the bolt engages its nut class correctly and accepts a flat-head driver for installation. Thread major diameter is compared to your specification during first-piece check and slot width is verified during in-process checks; both are documented on the inspection record before shipment. Produced at Ningbo Shengchuan Metal Products' Cixi facility using CNC turning and milling, the hexagonal head body, slotted drive, and partially threaded shank are produced to your latest drawing release. Thread class and shank diameter are verified against your callout. Applications span railway vehicle fastener systems, transportation equipment structural connections, and OEM heavy-duty mechanical assemblies. We can quote once we have ; our Cixi team will return a quotation and lead time from your drawing. The manufacturing facility covers close to 35,000 m².
