Stainless Steeel 304 M5x0.8 Slotted Pan Head Screws with Shoulder
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.
Like other screws, shoulder screws are meant to hold objects together and in position. However, they do not have a tapered shank, so they do not self-thread into soft materials. They are used in instances where pre-tapped holes require alignment with some tolerance. This allows the workpieces either a joint, pivot, or sliding motion. These screws are available in metric and imperial units.Shoulder screws have three sections: head, shoulder, and thread. The head is the largest diameter section of the shoulder screw, which prevents the screw from being inserted further than its length, and provides a bearing surface, as well as a drive mechanism (slotted, hex, etc.) so the screw can have torque applied for its installation. The shoulder is the smooth, middle section of the screw which contains the lateral movement of the workpieces. The threaded section has helixed grooves that have a major diameter slightly smaller than the shoulder diameter. This section is for insertion into a mating thread, be it a nut or tapped hole.
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.
