Hex Socket Head Shoulder Screws M6 A2 Screws on JIS Standard

1.Product Description

The Hex Socket Head Shoulder Screws is a hex socket screw with shoulder or step, also called step screws. Some of the shoulder screw have a kurled head and some just have a smooth surface.  A hex socket shoulder screw is a type of fastener, sometimes similar to a bolt, typically made of metal, and characterized by a shoulder or step, known as a external thread.  Shoulder screws are a type of machine screw with precise threads that are only half or less of the screw. A shoulder screw has a partially smooth shank that will allow the parted material some rotation and movement around the screw axis, as the threaded end will typically have a nut to maintain the position. These shoulder screws must be used with drilled holes and are common in machinery with vibration and heat variations. These are also called stripper bolts.A shoulder screw is an inclined plane wrapped around a nail. Some screw threads are designed to mate with a complementary thread, known as a internal thread, often in the form of a nut or an object that has the internal thread formed into it. Other screw threads are designed to cut a helical groove in a softer material as the screw is inserted. The most common uses of screws are to hold objects together and to position objects. The collar of the machine screw help to reducing the chance of damage to the part, and making it fasten firmly as a result of an uneven fastening surface.

3.Application

A shoulder screw has a partially smooth shank that will allow the parted material some rotation and movement around the screw axis, as the threaded end will typically have a nut to maintain the position. These shoulder screws must be used with drilled holes and are common in machinery with vibration and heat variations.  These fasteners are often used with nuts but also often driven into tapped holes without nuts. They might be considered a screw or a bolt based on the distinction. General Fastening applications where need high strength and superior corrosion resistance. 

4.Advantages

Common chioce for fastening, which provide high tensile, offering high holding power and corrosion resistance and don't need any coating. Competitive prices with professional factory supply. Perfect fastening solution with 10 years experiences to solve your problem: Wide range of parts selection. Durability testing and critical technical design to enhance fasteners lifetime.
