Hexagon Socket Head Cap Screws with Low Head with Reduced Loadability

The DIN7984 12.9 grade internal hexagonal flat-head cylindrical head screws (M3-M22) are made of high-strength alloy structural steel and undergo special heat treatment to achieve 12.9 grade mechanical properties. The screw heads adopt a low-flat design, with a height approximately 20%-30% lower than the standard cylindrical heads, ensuring excellent internal hexagonal driving performance even in limited installation spaces. The surface is blackened, featuring both basic rust prevention and low reflectivity properties. They are suitable for industrial scenarios such as precision machine tools, mold manufacturing, and automated equipment that have strict requirements for space limitations, connection strength, and appearance consistency.

The screws produced by Jinghong Fasteners comply with the DIN7984 standard. They are made of 12.9 grade high-strength alloy steel, with high hardness and excellent tensile strength. The short head design effectively saves installation space and is suitable for compact and narrow structures. The internal hexagonal slot type facilitates torque transmission and enables efficient installation. The blackening treatment on the surface has certain anti-corrosion and wear-resistant properties. The overall size accuracy is high, and due to the low-load design, they are more suitable for light to medium load fastening scenarios.
