Pan head machine screws are essential components in precision engineering and industrial assembly, offering a wide bearing surface and low-profile finish. Characterized by their rounded head with a flat underside, these screws are frequently used in metal-to-metal or metal-to-plastic applications, especially where flush installation is not required.
Typically manufactured from carbon steel, stainless steel (A2-70, A4-80), or brass, pan head machine screws are available in thread sizes from M2 to M10 and lengths ranging from 4mm to 100mm. Drive types include Phillips, slotted, torx, and allen head (hex socket), with options such as tamper-resistant variants for added security. Surface finishes include zinc-plated, nickel-plated, black oxide, or passivated stainless for corrosion protection and aesthetic consistency.
These screws often meet international standards like DIN 7985, ISO 7045, or ANSI B18.6.3, making them compatible with automated assembly systems. With precise threading and uniform tolerances, pan head machine screws ensure stable fastening in electronics, appliances, automotive panels, and enclosures.
The combination of structural reliability and versatile configurations makes pan head machine screws a preferred solution in both commercial manufacturing and OEM sectors.
