Metric Slotted 18-8 Stainless Steel Precision Shoulder Screws, With a shoulder that's twice as precise as standard shoulder screws, these metric shoulder screws act as a shaft or axle for bearings and other moving parts in applications that require smooth and accurate movement, such as measuring and lab equipment. Their head keeps the rotating and sliding parts in place. You can also use these screws as alignment guides in punch-and-die mechanisms, plastic-injection-mold sets, and other linear motion applications. Made of 18-8 stainless steel, they're nearly as strong as steel but won't rust in outdoor or washdown environments. Shoulder screws are sometimes known as shoulder bolts and stripper bolts.
Screws with a low profile have a head height that's about two-thirds the head height of a standard shoulder screw. They can be used in low-clearance applications such as inside machines. These screws meet DIN 923, an international standard for shoulder screw dimensions.
