M5 x 40mm Captive Socket Cap Head Screw | Similar to DIN 912 | A4 Stainless Steel
Designed for general engineering applications requiring retained fasteners, this M5 x 40mm socket captive screw combines a socket cap head with a reduced captive section. Once installed with a suitable retaining feature, the screw can be loosened from its mating thread while remaining associated with the panel or component. 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
- Jigs and Fixtures: Keeps adjustment or access fasteners associated with suitable workshop fixtures and production tooling.
- 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.
