Precision shoulder screws are a type of fastener that are widely used in robotics and automation applications. These screws are designed with a cylindrical shoulder that provides precise alignment and support, making them ideal for use in applications that require accurate positioning and secure attachment. In this blog, we will explore how precision shoulder screws are used in robotics and automation, and what factors to consider when purchasing them for industrial applications.
Precise Alignment
One of the primary benefits of precision shoulder screws is their ability to provide precise alignment in robotic and automation applications. The shoulder of the screw acts as a guide for the mating component, ensuring that it is aligned precisely and securely. This is particularly important in applications that require accurate positioning, such as pick-and-place operations or assembly lines.
Secure Attachment
Another key benefit of precision shoulder screws is their ability to provide secure attachment. The shoulder of the screw creates a stop against the mating component, preventing it from moving or rotating. This is particularly important in applications that involve high levels of vibration or stress, as it ensures that the components remain securely attached and in place.
Material
When selecting precision shoulder screws for robotics and automation applications, it is important to consider the material from which they are made. Stainless steel is a popular choice due to its corrosion resistance and high strength, but other materials such as titanium and aluminum may be more suitable for specific applications. The material chosen should be strong enough to withstand the forces and stresses involved in the application, while also being compatible with any other materials it will be in contact with. The most popular and available material is 18-8/300 series stainless steel.
Size and Thread Type
The size and thread type of the precision shoulder screw is also an important factor to consider. The screw must be the correct size and thread type to fit the mating component, and to provide the necessary strength and support. It is important to ensure that the screw is compatible with the other components in the application, and that it is the correct size to provide the required level of support.
Head Type
The head type of the precision shoulder screw is also an important consideration. Different head types are available, including hex, slotted, and Phillips, each with its own advantages and disadvantages. It is important to select the head type that is best suited to the specific application, taking into account factors such as accessibility, torque requirements, and aesthetics.
Precision shoulder screws are a critical component in many robotics and automation applications, providing precise alignment and secure attachment. When selecting these screws for industrial applications, it is important to consider factors such as material, size and thread type, head type, and application requirements, to ensure that the screws provide the necessary strength and support, and can withstand the forces and stresses involved in the application. With the right precision shoulder screws, robotics and automation applications can operate with precision, accuracy, and reliability.
How to order
When ordering Precision Shoulder screws, specify the Shoulder Diameter, Shoulder length, thread size, material and drive type. For example, an example of a typical Precision Shoulder screw is a ¼ shoulder x ½ long x 10-32 thread in SS18-8 with a hex-socket drive. Non-locking is the most popular style, but locking may also be available.
Precision Shoulder Bolts often show up under their OEM brand name. Some of the most popular brands include: BERG, Concord, Globe, PIC, Lyn-tron and RAF. A comprehensive selection of Shoulder Screws is also offered by McMaster-Carr (tight tolerance series), MSC and Grainger.
Finally, Precision Shoulder Screws can also show up under their Mil-spec numbers, which include MS51575 & MS51576 and are DFARS compliant with full paperwork.
