Product Description
Plain Drywall Screw (GB/T 14210-1993)

We are a professional manufacturer of machine screws. We have capabilities to manufacture machine screws in length 
of 1/4" to 8" and diameters of up to M2 to M6.3. Materials of low carbon steel from C1022.
We are able to achieve and fulfill customers' demands. If you have interests in our machine screws or more questions, 
please don't hesitate to contact us.
ASME standards specify a variety of "Machine Screws" in diameters ranging up to 0.75 in (19.05 mm). These fasteners
are often used with nuts as well as driven into tapped holes. They might be considered a screw or a bolt based on the 
Machinery's Handbook distinction. In practice, they tend to be mostly available in smaller sizes and the smaller sizes are 
referred to as screws or less ambiguously as machine screws, although some kinds of machine screw can be referred to 
as stove bolts.
