Self-Drilling Screw, #12 x 1-1/2 in, Steel Flange Hex Head External Hex Drive, 300 PK

The TEKS - 21422 is a Self-Drilling Screw, intended for use in materials without requiring pre-drilled holes. This type of fastener is commonly used in industrial and commercial settings such as metal fabrication, construction, and assembly. The design of the screw aims at facilitating fastening, potentially reducing labor time and effort compared to traditional screw types.

• Drive: External Hex – this indicates that an external hex tool is needed for installation or removal of the screw.
• Fastener Length: With a length of 1-1/2 inches, this indicates its potential depth of penetration and ability to join materials together.
• Head Dia.: #12 – this measurement across the widest part of the screw head provides an indication of how much surface area will be covered when fully inserted.
• Head Type: Flange Hex – this shape or design is intended for compatibility with specific tools or appropriateness for certain materials and applications.
• Material: Constructed from Steel which contributes towards its strength, corrosion resistance, and potential suitability for particular industrial applications.
• Materials for Use With: Intended primarily to penetrate and possibly secure Metal materials in different industrial contexts.
• Screw Size: #12 – Indicates its width & thread count per inch that contribute towards fitting into material during attempts at securing them in an industrial setting
• System of Measurement: Uses Inch (imperial) system to determine size and length
• Tip Type: Drilling – End designed aiming at being suitable for self-drilling application without necessarily requiring pre-drilled holes
