Cross Recessed Pan Head Tapping Screw

A variety of domestic and international standards apply to the Cross Recessed Pan Head Tapping Screw, including national, regional and international specifications:

1.Chinese National Standard: GB/T 845, the core standard in China, which governs dimensions and technical requirements of the Cross Recessed Pan Head Tapping Screw for civil and general industrial use.

2.International Standard: ISO 7049, a worldwide recognized standard for the Cross Recessed Pan Head Tapping Screw, widely adopted for export products.

3.German Standard: DIN 7981, the mainstream standard in European markets and commonly used for Europe-bound orders of the Cross Recessed Pan Head Tapping Screw.

4.American Standard: ANSI/ASME B18.6.3, applicable to North America, specifying sizes, threads and mechanical properties of the product.

5.Japanese Standard: JIS B 1122, widely used for Japanese supporting products.

All above standards clearly define the overall dimensions, thread specifications, mechanical properties, surface treatment and test methods of the Cross Recessed Pan Head Tapping Screw, serving as essential guidelines for production, inspection and export delivery.

Our Cross Recessed Pan Head Tapping Screw is widely used for fastening light-duty and thin-walled components such as thin steel plates, galvanized sheets, plastic parts, wood panels and aluminum alloy profiles. It is commonly applied to assembly of home appliance shells, electronic fittings, furniture parts, small hardware, lamps and kitchen & bathroom products. This fastener suits mass assembly and regular indoor structural connection. The Cross Recessed Pan Head Tapping Screw is not recommended for connections requiring heavy load bearing, thick hard metal, or working environments with severe corrosion, high temperature and high pressure.

Our Cross Recessed Pan Head Tapping Screw has prominent practical advantages. Its cross recess design ensures even force bearing and prevents slipping during installation and removal, and it is compatible with common cross screwdrivers for excellent versatility. The pan head has a smooth round surface. After installation, the Cross Recessed Pan Head Tapping Screw fits closely with workpieces, presenting a neat appearance without sharp edges that may cause scratches. As a self-tapping fastener, it can be screwed into substrates directly without pre-tapping or matching nuts, which greatly simplifies assembly procedures and improves working efficiency. Featuring compact size, the Cross Recessed Pan Head Tapping Screw fits narrow mounting spaces. It delivers reliable connection performance and anti-loosening capacity, meeting the demands of civil and general industrial assembly with a low overall application cost.

The overall processing difficulty of the Cross Recessed Pan Head Tapping Screw is moderate, and it is a standardized mass-produced fastener. Wire cold heading is the core process, and the integral forming of pan head and screw shank is mature with low technical barriers for standard sizes. The cross recess is formed by stamping, and the die precision directly affects the quality of the recess, so stable dies are required for mass production. Threads are formed by thread rolling, which can ensure regular thread profiles easily. The processing difficulty of the Cross Recessed Pan Head Tapping Screw will increase for extra-small sizes, fine threads, special surface treatments or products with ultra-high hardness requirements, which demand higher precision of equipment, heat treatment and surface treatment technology and cannot be produced on ordinary production lines. For standard general models, the Cross Recessed Pan Head Tapping Screw enjoys mature processes, high yield rate and low processing difficulty.
