ProClip USA 100223 Universal M4 Fastener Pack

Create secure M4 mounting connections with a choice of three supplied screw lengths. ProClip USA 100223 includes four low-profile M4 screws in each of the 10, 14 and 20 mm lengths, letting an installer select the reach needed for the mounted components and their combined material thickness. The low-profile screw head uses a 2.5 mm hex drive. The pack includes four M4 lock nuts, four flat washers and four lock washers. Flat washers spread clamping load at the mounting surface, while lock washers and lock nuts support retention where a fastening point is subject to movement or vibration. A 2.5 mm Allen wrench is included for driving the supplied screws without requiring a separate hex key. Use the hardware where an M4 fastener is required to join compatible mounting components, holders, brackets or other equipment with matching mounting holes. Rather than limiting an installation to one screw length, the pack provides 10, 14 and 20 mm options in the same set. This helps accommodate different stack heights while retaining consistent M4 thread sizing and a low-profile fastener head.
