S-99136A600 Length 2 1/2" Drywall Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc yellow-chromate plating, extending service life in various environments
• Enhanced thread-holding power through thread forming technology that creates strong, permanent connections in drywall and wood
• Optimized installation efficiency with Phillips No. 2 drive for secure tool engagement and reduced cam-out
• Reduced material splitting thanks to partial threading design that concentrates holding force where needed most
• Flush finishing capability with standard flat head profile that sits neatly below surface level
• Reliable penetration performance with pointed tip design for easier starting and straight driving
• Versatile application range with 2-1/2" length suitable for various drywall and wood fastening requirements

Professional Applications & Engineering Value

These No. 8 drywall screws are engineered to address common installation challenges in construction and woodworking applications. The zinc yellow-chromate plated steel construction provides exceptional corrosion protection, making them ideal for interior environments where moisture resistance is crucial. The thread forming technology eliminates the need for pre-drilling in many applications, as it displaces material rather than removing it, creating stronger thread engagement and reducing the risk of loose fittings over time. The partial threading design ensures maximum clamping force while minimizing the potential for material splitting in drywall and wood substrates. With their Phillips flat head configuration and precise 9 threads per inch pattern, these screws deliver consistent performance for professional drywall installation, wood framing, and general construction fastening needs where reliable, long-term holding power is essential.

Specification Summary & Compliance

These drywall screws feature a 0.164" thread diameter with 9 threads per inch in a right-hand thread configuration. The 2-1/2" length provides optimal penetration for standard drywall applications, while the partially threaded design ensures proper clamping force. Manufactured to industry standards for drywall and wood fastening applications, these screws comply with relevant construction fastener specifications and feature zinc yellow-chromate plating that meets corrosion resistance requirements for interior building applications.
