Carbon steel GB 831-1988 Slotted Headless Screw, JX-21JG509-M6-12-D8-ST

Name: Headless Alloy Steel Precision Shoulder Screws

Without a head to get in the way, these screws fit in tight spaces where standard shoulder screws cannot. Either thread them in a countersunk hole for a flush mount or install them with the shoulder sticking out to use them as pins or dowels for aligning and locating components. With a shoulder diameter that is more precise than our general-purpose shoulder screws, these screws are a good choice for measuring devices, optical fixtures, laboratory equipment, and other applications where precision matters. Made of alloy steel, they are strong and resist wear. Metric screws meet DIN 927, an international standard for slotted shoulder screw dimensions.

Material: Steel 1215 Machined Parts

 Manufacturing has a reputation for machining quality parts from 1215 Steel. We can machine intricate parts on our CNC Swiss machines and CNC turning centers. Steel alloy 1215 is a popular free-machining alloy (FMA), ideal for parts that require considerable machining and a bright finish. It responds well to slight bending, threading, and nibbling, but is not ideal for parts that may be subject to very severe fatigue stress.1215 has a machining cost factor of 1.2 when compared to steel 12L14. It possesses better weldability and formability than 12L14. 1215 can be heat treated.

Packing: Inner is Poly foam, out is carton. Then pallet. Carton size: 29*19*19.5CM and 23.5*17.5*8, CM and pallet size is: 215*100*90CM, or as your requirement.
