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 from Fastenright, with optional thread locking patches available.
Thread diameters from M3 to M12 and lengths ranging from 12mm to 120mm.
Non-standard sizes and materials are available to order, including custom parts made to drawings.
d1 and L1 dimensions can be to customer specification.
