## Summary description

Machine screw M4×12 manufactured to DIN 912 with a cheese-style head and 3 mm internal hex socket. Designed for mechanical assemblies where a compact head and hex drive are required. Suitable for metal and plastic components, offering reliable fastening in maintenance, assembly, and repair tasks. Supplied individually without surface finish specified.

## Long description

Screw M4×12 DIN 912 — cheese head, hex socket 3 mm is a machine screw produced to DIN 912 specifications. It features an M4 thread with a 12 mm overall length and a compact cylindrical (cheese-style) head with a 3 mm internal hex drive. The fastener is intended for mechanical assemblies where a low-profile head and hexagonal drive allow secure tightening with an Allen key or hex driver. It is suitable for joining metal and plastic parts in assembly, repair and maintenance operations. The product is supplied individually and no specific surface finish is declared in the product data.
Advantages
The cheese-head M4×12 DIN 912 screw provides a compact head profile that minimizes protrusion above the mating surface while maintaining sufficient bearing area. The 3 mm hex socket enables controlled torque application and reduced risk of cam-out compared with slotted or Phillips drives. Conformance to DIN 912 ensures consistent thread and head dimensions for interchangeability in mechanical assemblies. Its suitability for metal and plastic components offers versatility across repair and assembly tasks.

How to use
Select an appropriate 3 mm hex key or hex bit driver that fits the internal hex socket without play. Pre-thread or pilot-drill mating components as required by material and application, then insert the screw and tighten by hand initially to align parts. Apply torque using the hex key or driver until the assembly is secure; avoid excessive torque to prevent thread stripping or damage to plastic parts. For metal-to-metal joints, use appropriate torque values for M4 screws and consider using threadlocker if vibration resistance is needed. For countersunk or flush applications, ensure mating surfaces accommodate the cheese head profile.
Usage recommendations
For reliable fastening, match screw length and thread engagement to the component thickness: ensure at least one full thread engagement per screw in the receiving material for plastic and two or more in thin sheet metal. When assembling into soft plastics, reduce torque and consider using washers to distribute load. If corrosion resistance is required, select a surface-finished or corrosion-resistant alternative as this product is supplied without a specified finish.
