DIN 933 A2 Stainless Steel Fully Threaded Hex Head Bolts M3–M14, 8–120 mm
DIN 933 hex head bolts are manufactured from A2 stainless steel and designed for mechanical fastening applications requiring a fully threaded shank. The external hexagonal head allows tightening and removal using a suitable wrench or socket.
The full-length metric thread provides threaded engagement with compatible nuts or pre-threaded holes. Unlike partially threaded DIN 931 bolts, these DIN 933 bolts do not have a long, smooth unthreaded shank section.
A2 stainless steel provides corrosion resistance for general mechanical, equipment and assembly applications, including indoor and outdoor installations where this stainless steel grade is suitable.
The range includes 59 dimensional configurations with eight nominal metric thread sizes from M3 to M14. Available lengths range from 8 to 120 mm depending on thread size. Each version is identified by an individual FNI part number.
