Pot Magnets: The "No-Drill" Fastening Solution That Transforms Industrial & Warehouse Workflows
Imagine this: You need to mount a 50kg tool rack on a metal warehouse wall. Drilling would take 20 minutes (plus cleanup) — and leave permanent holes. What if you could do it in 30 seconds, with zero damage?
That’s the power of neodymium pot magnets — the industrial-grade magnetic fasteners that replace drills, bolts, and hassle.
What Are Pot Magnets (And Why Do You Need Them)?
Pot magnets (or "cup magnets") are high-strength neodymium magnets encased in a steel shell. This casing doesn’t just protect the magnet — it concentrates magnetic flux, boosting holding strength by 30% compared to bare magnets.
Whether you’re securing heavy equipment, organizing tools, or mounting outdoor signs, pot magnets solve 3 big pain points:
- No drilling = no surface damage (critical for rental spaces or expensive machinery)
- Instant installation (30 seconds vs. 20+ minutes for traditional fasteners)
- Reusable & repositionable (move fixtures without patching holes)
5 Pot Magnet Types For Every Job
We offer 5 tailored designs to fit your exact mounting needs:
1. Countersunk Hole Pot Magnets
- Design: A flush screw hole (no protruding hardware)
- Best For: Outdoor signs, equipment panels, or any surface where a clean, low-profile look matters.
- Pro Tip: Pair with stainless steel screws for rust-resistant outdoor use.
2. Internal Thread Pot Magnets
- Design: Built-in nuts (M4-M10) for secure, permanent fastening
- Best For: Heavy equipment fixtures (up to 150kg holding strength) or industrial clamps that need to stay put.
3. External Stud Pot Magnets
- Design: A built-in screw stud (M3-M8) for quick assembly
- Best For: Shelf mounting, double-layer structures, or projects where you need to "snap and secure" components.
4. Blind Hole Pot Magnets
- Design: A simple hole (no threads) for self-tapping screws
- Best For: Temporary tool hooks, lightweight fixtures, or quick repairs.
5. Internal Stud Pot Magnets
- Design: A hidden stud (recessed into the casing)
- Best For: Precision equipment positioning or hidden mounting (no visible hardware).
Why Our Pot Magnets Outperform The Rest
Not all pot magnets are created equal. Here’s what makes ours the go-to choice for industrial teams:
- Top-Tier Strength: N52-grade neodymium (the strongest commercial magnet) + steel casing = a 50mm magnet holds 80kg (that’s 2 full propane tanks!).
- Built To Last: Ni-plated steel casing resists rust, impact, and wear — tested to survive 10+ years in warehouse/industrial environments.
- Customizable: Need a specific thread size (e.g., 1/4"-20 imperial) or diameter? We handle custom orders with a 50-unit MOQ (no minimum for standard sizes).
- Fast Turnaround: Get samples in 5 days, bulk orders in 12 days — no waiting for overseas factories.
