Self-Drilling Screw, 1/4" x 2-1/2 in, Zinc Plated Steel Flange Hex Head External Hex Drive, 50 PK

The ZORO SELECT - U31810.025.0250 is a self-drilling screw intended for use in steel-to-steel applications. Constructed of steel and featuring a drill point at the end, these screws may be driven directly into materials without pre-drilled holes. This feature potentially allows their use in various industrial tasks like metal fabrication, construction, and assembly.

• Drive: The external hex drive requires a 3/8 in tool fitting for installation or removal.
• Fastener Length: With a length of 2-1/2 in, it determines how deeply it can penetrate and secure materials together.
• Finish: The Zinc Plated finish is intended to improve durability and corrosion resistance while providing certain functional properties like potential improvement in grip or reduction in friction during installation.
• Head Type & Size: Flange Hex head type with diameter ranging from 0.305 in to 0.312 in is designed for appropriate load distribution when fully inserted.
• CAD Available: A Computer-Aided Design (CAD) file is available for accurate incorporation into digital project plans.
• Screw Size & Thread Style: A screw size of 1/4", featuring a fully threaded style suggests that threads extend along the entire length of the screw which could provide secure fastening within industrial applications.
• Standards Compliance: Complies with IFI-113/ASME B18.6.4 standards suggesting adherence to established technical specifications related to design, safety and performance
