Phillips Pan Head Reduced Thread Captive Screws, a variation of DIN 7985H standard, are a unique style screw that cannot be fully removed post installation.
When combined with Threaded Captive Washers, components are fixed between the head of the screw and the washer to create a self-retaining fastener.
They are required by EU Machinery Directive 2006/42/EC for certain types of machinery and safety equipment e.g. guard panels and safety guards.
Manufactured from A2 / 304 Stainless Steel and A4 / 316 Stainless Steel as standard. Other materials are available to order such as Aluminium, Titanium and Phosphor Bronze.
