ASME/ANSI B18.6.1 (T6):1997 Oval Countersunk Head Slotted Wood Screw
ASME/ANSI B18.6.1 (T6):1997 Oval Countersunk Head Slotted Wood Screw features a U.S.-standard slotted oval countersunk wood screw design, making it suitable for wood assemblies that must match North American drawings, spare part systems, or export products.
The oval countersunk head creates a smooth rounded transition on the timber surface, combining clamping and appearance, while the slot supports traditional installation and fine adjustment. This structure supports efficient assembly while balancing joint stability, load distribution, and convenient maintenance, making it practical for standardized purchasing and volume production.
This product can be used in furniture, decorative joinery, wooden door hardware, instrument accessories, and small wooden products. Inch lengths, head finish, and corrosion-resistant materials can be selected to meet requirements for corrosion protection, wear resistance, assembly efficiency, and long-term reliability.
