Description
The Cross Recessed Pan Head Machine Screw is a precision-engineered machine screw designed to fasten components securely in pre-tapped holes or with nuts. Manufactured from high-quality 304 stainless steel, it offers excellent corrosion resistance, high hardness, and long-term durability. This screw features a cross recessed (Phillips) drive for easy installation and removal, along with a pan-shaped, roundness-style head that provides a clean, professional finish. Compliant with GB818 standards, it ensures dimensional accuracy and consistent quality for industrial and commercial applications. These screws are widely used in electronics, appliances, general manufacturing, and other applications where a secure, flush, or slightly protruding head is acceptable, and corrosion resistance is desired.
Features & Benefits
- High Corrosion Resistance: Constructed from 304 stainless steel, these screws are highly resistant to wear, rust, and oxidation, making them suitable for use in humid or challenging environments.
- Secure & Stable Fastening: The deep, uniform screw threads ensure a tight, even force distribution, and the standard cross groove design prevents slipping during tightening.
- Durable & Practical: With high hardness and no deformation, these screws are both aesthetically pleasing and functional, maintaining their integrity under stress.
- Versatile Design: The pan head shape provides a good grip surface and a clean, finished appearance. These screws are designed for use in pre-tapped holes in metal and other materials.
