M2.5 x 18mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
For transport equipment, inspection panels and removable covers, this M2.5 x 18mm captive machine screw provides a retained fastening format that can reduce loose screws during servicing or repeated access. The H2 hex socket gives positive tool engagement while the 4.5mm head diameter and 2.5mm head height follow a DIN 912-style cap head geometry. A4 Stainless Steel provides enhanced corrosion resistance for suitable outdoor, washdown, coastal and marine applications where a higher level of environmental resistance is required.
What Are Captive Socket Cap Head Screws?
Captive Socket Cap Head Screws are specialist fasteners designed to stay attached to a panel, cover or component after the threaded portion has been loosened. A reduced captive section works with a compatible panel, washer, sleeve or retaining feature so the screw can remain retained instead of falling free.
Common Applications
- Machinery Guards: Keeps compatible screws attached to removable guards during inspection, adjustment and maintenance.
- Control Cabinets: Retains panel fixings on electrical and automation enclosures that require repeated access.
- Equipment Covers: Supports serviceable covers where loose screws could be dropped inside machinery or misplaced.
- Maintenance Panels: Helps keep fastening hardware associated with access panels during routine servicing.
