- How Drywall Screws Are Made
Drywall screws are typically manufactured from low-carbon steel wire. The process includes wire
drawing, cold heading to form the bugle head, thread rolling, heat treatment to develop a hard
surface and tough core, quality inspection and packing. Consistent manufacturing ensures reliable
driving performance and reduced breakage.
- Applications
Drywall screws are used to fasten gypsum boards to light-gauge steel studs and wooden framing.
Common applications include false ceilings, drywall partitions, interior fit-outs, commercial
buildings, residential construction and renovation projects. Fine thread screws are generally used
with metal studs while coarse thread screws are preferred for timber.
- Hardness Specifications
Industry practice is to produce a hard case with a tougher core. For many drywall screws, typical
targets are surface hardness around 550–800 HV and core hardness around 300–450 HV after
heat treatment. Actual requirements depend on the applicable product standard and screw size.
- BIS Standards
Manufacturers supplying the Indian market should refer to IS 18507:2024 for drywall screws. The
standard covers dimensions, material, mechanical properties, testing, marking and quality
requirements. Always consult the latest official BIS publication before claiming compliance.
- JIS Standards
Customers may request compliance with Japanese Industrial Standards. JIS B 1125 is commonly
referenced for drywall screws, with additional JIS fastener standards applicable depending on the
product. Verify the customer’s specification before production.
- Tips for Selecting Drywall Screws
Choose fine thread screws for metal studs, coarse thread screws for wood, and an appropriate
screw length based on gypsum board thickness and the supporting member. Proper installation
improves holding strength and finish quality.
