M3.5 x 30mm Captive Socket Cap Head Screw | Similar to DIN 912 | A2 Stainless Steel
This M3.5 x 30mm retained cap head screw is designed for machinery guards, equipment covers and service panels where the fixing needs to remain attached after it has been loosened. The 7.0mm threaded length provides the fastening section while the reduced 2.6mm captive diameter is intended to work with a compatible panel, washer, sleeve or retaining feature. A2 Stainless Steel provides good corrosion resistance for general engineering, machinery, equipment and indoor or suitably protected external applications.

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

- Laboratory Equipment: Supports retained panel fixing on instruments and serviceable technical equipment.
- Fabricated Housings: Provides a captive fastening format for custom covers, guards and equipment enclosures.
- General Engineering: Useful where a screw needs to remain attached to the assembly after disengaging from its mating thread.
