Prev: Knurled Captive Shouldered Thumb Screws 
These Low Cap Head Captive Screws are similar to Cap Head Captive Screws, but host a modified head which is ideal for applications and assemblies where space is limited.
They feature an unthreaded portion below the screw’s head, which aid the screws self-retaining nature – meaning they can only be partially removed.
Often found in industrial machinery and military applications, they are also often required by EU directives on a number of pieces of machinery and safety equipment and must be applied to equipment such as safety guards.
Available as standard in A2 and A4 stainless steel, with optional thread locking patches available.
We are able to provide specials in a range of sizes, materials and finishes.
