M2.5 x 25mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Made for repeat-access assemblies, this M2.5 x 25mm stainless steel captive screw uses a reduced 1.8mm section between the threaded portion and head area. When paired with a compatible captive feature, this allows the fixing to remain with the panel after disengaging from the mating thread. 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?
Socket Head Captive Screws provide positive hex-key drive engagement together with a retained fastening format. They are commonly specified for machinery, enclosures and serviceable equipment where panels need to be removed or opened regularly without losing the fasteners.
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.
