Custom Sealing Screws: Industrial Waterproof Fasteners
What You Can Get (Specs & Custom Options)Products
•Sizes we work with: Threads from M2 to M20, lengths 5mm–100mm, head styles (pan, round, flat) — and if you need something off-book (weird thread pitch, unique head diameter), send over your drawing; we’ll make it.
•Seal gaskets to match your space: Pick NBR (for oil-heavy areas), EPDM (outdoor/wet spots), silicone (high-heat gear), or Viton (chemical-resistant setups) — no generic gaskets here.
•Base materials & finishes: 304/316 stainless steel (won’t rust in damp spots), carbon steel (for heavy strength); finishes like zinc plating (extra rust protection) or passivation (tougher against corrosion).
01
Hydraulic/pneumatic gear
Seal valve covers or cylinder parts so hydraulic oil stays put (no messy, expensive leaks).
01
Outdoor electrical boxes
Lock junction boxes/sensor housings tight — rain and dust won’t fry your equipment.
01
Chemical processing machines
Fasten reactor lids or pipeline flanges — corrosive liquids won’t seep out (or in).
01
Medical gear casings
Keep sterile environments sterile — no dust or moisture getting into sensitive instruments.
How We Make Them (And Keep Them Good)Products
Our build process:
Cut raw material, then cold-head to shape the screw (tough, no weak spots).
Roll threads (way more precise than cutting — threads hold tighter).
Press-fit gaskets with machines (no loose seals from hand-fitting).
Add finish (plating/passivation) then check every part.
How we make sure they don’t fail:
Measure every screw (calipers, thread gauges) — no “close enough” sizes.
Pressure-test seals (up to 10MPa, 24 hours no leaks).
Salt-spray test (48–120 hours) — if they rust, we scrap ’em.
Quick Tips for Installing (So They Work Right)Products
1. Wipe the mounting surface clean first (no dirt or oil under the gasket — that kills the seal).
2. Use a torque wrench (don’t crank it too hard — you’ll crush the gasket and ruin the seal).
3. For hot/chemical spots: Check the seal every 6–12 months (swap the gasket if it looks cracked/dry).
Why Pick Us Over Generic Screws?Products
•Your specs, fast: Non-standard designs can be sampled within half a month, without the need to wait for a long time for mold opening.
•No batch surprises: Whether you need 100 or 100,000, every screw’s the same quality.
•We help you pick: Not sure which material/gasket? Tell us your setup — we’ll point you to what works.
