8-18X1/2" BIT TIP SCREWS 1K/PK

🧾 What it is:

A bulk box of hex or pan-head self-drilling screws used for fastening metal-to-metal or metal-to-wood without pre-drilling.

🔧 Breaking it down:

• 8 → Screw diameter (#8 size)
• 18 → Thread pitch (18 threads per inch, sheet metal thread)
• 1/2" → Screw length
• BIT TIP → Self-drilling (built-in drill point eliminates pre-drilling)
• 1K/PK → 1,000-piece bulk pack (jobsite/contractor supply)

🔧 What it’s used for:

These screws are commonly used in:

• HVAC ductwork and sheet metal assembly
• Electrical conduit straps and boxes
• Metal studs and light framing
• Signage and brackets
• General mechanical fastening

⚙️ Key features:

• Self-drilling tip (cuts its own hole in metal)
• Saves time—no pilot hole needed
• Zinc-plated for corrosion resistance
• Designed for thin-gauge steel and sheet metal
• Bulk packaging for contractors and large jobs

🧠 Simple explanation:

It’s basically a box of sharp-tip screws that can drill right into metal without pre-drilling, used for HVAC, electrical, and general construction work.
