1.2mm PCB Internal/External Thread Super Screw

Product Description

The 1.2mm PCB Internal/External Thread Super Screw is a dual-thread fastener for boards that are too thin to accept conventional hardware. It carries an external thread for the nut side and an internal thread in the head, so a single component can clamp, space and connect boards in both directions.

The screw is produced from a high-hardness alloy and formed with a fine thread-rolling process. Rolled threads are stronger than cut threads because the material grain flows continuously along the thread flanks, giving high tensile strength and reliable locking behaviour even at this small size.

A key benefit on thin boards is deformation control. Because the fastener threads into both the board stack and the mating part, the clamping load is applied without bending the PCB — the screw prevents the deformation and stress that would otherwise damage traces and solder joints. Assembly stays precise inside extremely confined spaces.

Key Features & Benefits

• Dual-Thread Structure: External and internal threads allow bidirectional fastening from one component.
• Engineered for 1.2mm Substrates: Designed specifically for ultra-thin PCBs where standard hardware will not work.
• High-Hardness Alloy: Strong base material supports high tensile loads in miniature sizes.
• Fine Thread-Rolling: Rolled threads deliver stable locking and superior tensile strength.
• PCB Deformation Control: Clamping geometry prevents board bending and protects traces and joints.

Application Industries

Extensively used in ultra-thin laptops, tablets, wearable devices and high-density communication modules, these super screws are ideal for stacked assembly and precision structural fixing on thin PCBs.

They meet the stringent demands of lightweight, highly integrated electronics for secure fastening, and suit any design where boards must be stacked and locked without adding height or risking board flex.
