S-91555A113 Length 3/8" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with black-oxide steel coating, extending screw lifespan in various environmental conditions
• Superior holding power in fiberboard and particleboard through thread forming design that creates strong, permanent threads without pre-tapping
• Quick and efficient installation with fully threaded pointed tip and 13 TPI configuration for rapid penetration
• Secure fastening with reduced cam-out thanks to Phillips No. 2 drive system and pan head design
• Precision compatibility with standard 1/16" drill bits for perfect pilot holes and optimal material engagement
• Reliable performance in woodworking applications with rounded head profile that sits flush without damaging material surface
• Consistent dimensional accuracy with 0.138" thread diameter and 3/8" length for predictable results in repetitive applications

Professional Applications & Engineering Value

These black-oxide steel wood screws are engineered specifically for fiberboard and particleboard applications where traditional fasteners often fail. The thread forming technology eliminates the need for pre-tapped holes while creating stronger, more durable connections by compressing material fibers rather than cutting them. This approach significantly reduces material stress and prevents stripping in softer composite woods. The combination of fully threaded design and 13 TPI configuration ensures maximum thread engagement throughout the entire fastener length, providing exceptional pull-out resistance. The Phillips drive system with No. 2 size offers reliable torque transmission while the pan head design distributes clamping force evenly across the surface. These features make these screws ideal for furniture manufacturing, cabinet installation, and construction projects requiring reliable fastening in engineered wood products.

Specification Summary & Compliance

These screws feature precision inch system measurements with No. 6 screw size, 3/8" length, and 0.138" thread diameter. The thread forming tapping method and right-hand thread direction comply with standard wood screw specifications. Manufacturing follows industry standards for dimensional accuracy, with consistent 13 threads per inch and proper head diameter of 0.27" for reliable performance. The product meets relevant industry specifications for wood screw applications and is manufactured using compliant materials suitable for commercial and industrial use in woodworking and construction sectors.
