Applications

Industries Relying on Our Polymer Fasteners

Chemical Tank Lids

PTFE bolts and nuts for securing chemical storage tank lids and access hatches — fully resistant to acid fumes, solvents, and corrosive chemical splashes without degradation.

Semiconductor Wet Benches

PEEK and PTFE fasteners for wafer cleaning equipment and wet process tools — meeting semiconductor purity requirements with low outgassing and particle generation.

Food Processing & Outdoor Structures

FDA-compliant Nylon fasteners for food contact equipment and UV-resistant PVDF fasteners for outdoor structures — reliable performance without corrosion.

Why Choose Our Fasteners

Engineered for Corrosion-Free Fastening

Custom Head & Thread Design

Hex, socket, pan, flat, or fully custom head geometry — we machine to your exact tool interface and thread specification, not limited to standard catalog sizes.

Material Match Guarantee

We recommend PTFE for chemical resistance, PEEK for strength + temperature, PVDF for outdoor UV, or Nylon for economy — based on your actual operating environment.

Thread Quality Assurance

Every fastener undergoes thread gauge verification — M2 to M30 threads meet ISO metric thread standards with full dimensional inspection reports.

Kit & Assembly Programs

We supply complete fastener kits (bolt + nut + washer) in matched quantities, labeled and packaged per your assembly sequence — reducing your receiving and kitting labor.

Common Questions

Polymer Fastener Manufacturing FAQ

What types of polymer fasteners do you manufacture? +

We manufacture PTFE and PEEK fasteners including: hex head bolts, hex nuts, flat washers, socket button head screws, Phillips screws, slotted screws, double-ended studs, and fully custom fasteners. Choose PTFE for universal chemical resistance, or PEEK for high mechanical strength (100+ MPa) and 260°C continuous temperature. Thread sizes from M2 to M30 in ISO metric or UNF/UNC standards. We also supply matched fastener kits (bolt + nut + washer) for assembly-line efficiency.

Can you manufacture custom head types not found in standard catalogs? +

Absolutely. We CNC-machine any head geometry — hex, socket, pan, flat, button, or fully custom designs. Send us your drawing or sample fastener, and we'll replicate the exact head profile and drive type. Custom knurled heads and thumb screws are also within our capability.

What is the maximum length you can produce for PTFE threaded rods? +

We can produce PTFE threaded rods and long bolts up to 500mm in length. For longer requirements, contact us with your specifications — we can produce up to 1,000mm using specialized workholding.

Do you provide FDA-compliant PTFE fasteners for food processing? +

Yes. Our pure PTFE fasteners are available with FDA 21 CFR compliance and USP Class VI certification for food contact and pharmaceutical applications. Full material traceability and regulatory documentation included with every shipment.

What is your minimum order quantity for custom PTFE fasteners? +

We support prototype orders starting from 1 piece for design validation. Production quantities start at 50 pieces per size, with volume pricing available for 500+ and 5,000+ piece orders. We also offer kit programs where we package matched bolt-nut-washer sets for your assembly line.

How do PTFE fasteners compare to metal fasteners in terms of strength? +

PTFE fasteners have lower tensile strength (~20-30 MPa) compared to stainless steel (~500+ MPa), but provide unmatched chemical resistance in acids, solvents, and aggressive media where metals fail. For higher strength requirements, PEEK fasteners deliver 100+ MPa tensile strength while maintaining excellent chemical resistance and 260°C temperature capability — bridging the gap between pure PTFE and metals.
