Six-Lobe Pan Head Machine Screw

1.Base Material ：Carbon steel (1018/10B21), stainless steel (304/316) as main types, alloy steel (45H) for Dazhe Fastener’s China Six-Lobe Pan Head Machine Screw special working conditions, matching rust and tensile resistance requirements of different application environments.

2.Dimensional Accuracy ：Strictly implement GB/T 2672, ISO 14586, ANSI B18.6.3 standards; control head diameter/height, screw rod diameter, thread accuracy (go-no go gauge inspection), six-lobe slot depth and centering degree with high precision.

3.Six-Lobe Slot Processing ：Processed by special six-lobe milling cutters, with clear tooth profile, no burrs, and perfect fit with supporting Torx wrenches to avoid slipping during tightening.

4.Surface Treatment ：Carbon steel: galvanizing (blue-white zinc/color zinc), blackening, dacromet; stainless steel: natural color/passivation. All treatments enhance rust and corrosion resistance.

5.Auxiliary Parameters ：Customizable metric (M3-M12)/inch thread, screw rod length, and combined type with spring washer/flat washer.

Product Features of Six-Lobe Pan Head Machine Screw

1.Pan Head Design ：Dome head with straight side, fits tightly to the workpiece surface, uniform force bearing, no scratch to connected parts, neat appearance, suitable for assembly with surface flatness requirements.

2.Machine Screw Performance ：Matched with nuts or pre-tapped threaded holes, no additional tapping required, high assembly efficiency, tight thread engagement, and strong connection stability.

3.Material Compatibility ：Cost-effective carbon steel and acid/alkali/moisture resistant stainless steel meet the basic needs of most working conditions; non-standard materials can be customized for special requirements.

Core Advantage: Six-Lobe (Torx) Slot

Compared with cross slot, straight slot and ordinary hexagon slot, the six-lobe slot is the core competitiveness of this product, with exclusive advantages as follows:

1.Super anti-slip performance ：Surface contact between slot and Torx wrench (instead of point/line contact of cross slot), large force bearing area, no slipping or slot cracking during tightening, and can bear higher tightening torque.

2.Precise torque transmission ：High fit between wrench and slot, accurate transmission of tightening force, ensure fastening of connection, and avoid loosening caused by insufficient torque.

3.Anti-disassembly & misoperation ：Disassembly only with special Torx wrench, inaccessible to ordinary tools, effectively prevent random disassembly by non-professionals, and improve product/equipment safety.

4.High processing precision ：Good symmetry of the slot, easy alignment of wrench during assembly, suitable for batch assembly of automatic production lines, and improve production efficiency.

5.Low wear rate ：Surface contact reduces friction and wear between wrench and slot, prolong the service life of screws and tools.
