Vacuum-Vented Screws
Vented (drilled) socket-head cap screws that release trapped air and gases during pump-down to prevent virtual leaks in vacuum and cleanroom systems.
Industry
Precision couplings and special screws that help food and packaging machinery run hygienically and reliably under continuous wash-down.
Overview
Food and packaging machinery runs long hours under frequent, aggressive wash-down. Every drive component has to resist corrosion, survive cleaning agents and stay hygienic without losing precision. NBK Europe supplies stainless steel and chemical-resistant shaft couplings and special screws that hold up in exactly these conditions, protecting food safety and uptime at the same time.
Stainless and coated fasteners resist rust and repeated sterilisation, while flexible couplings keep conveyors, dosing and packaging drives running smoothly. Full specifications and CAD files are available per product on nbk1560.com. Tell us your cleaning regime and load, and we will match the right material and type.
Stainless, wash-down-safe components that protect food safety.

Dependable drive components for continuous production.

Vented (drilled) socket-head cap screws that release trapped air and gases during pump-down to prevent virtual leaks in vacuum and cleanroom systems.

One-piece slit couplings for cleanroom, vacuum and heat-resistant use: zero backlash, low particle generation and excellent chemical and corrosion resistance.

Grade 2 and Grade 5 titanium socket-head cap and machine screws: lightweight, non-magnetic and chemically resistant for medical, aerospace and semiconductor use.

One-piece spiral-beam slit couplings for precise speed and position control: zero backlash, high torsional stiffness, in aluminium or stainless steel.

Low-permeability fasteners in titanium, SUS316L HiMo, tantalum, phosphor bronze and brass for MRI, cryogenic, semiconductor and precision magnetic instruments.

Thin-walled metal bellows coupling for exceptional positioning accuracy: zero backlash and constant-velocity rotation with very low reaction forces on bearings.

Fasteners for service far beyond 200 °C: SUS316L, molybdenum, ceramic, Vespel, Hastelloy and Inconel screws for furnaces, plasma and high-temperature process equipment.

Heat-resistant, chemical-proof Oldham couplings with PEEK or VESPEL spacers for cleanroom and vacuum use: high misalignment tolerance and electrical insulation.

Screws that protect the thread and head against aggressive chemicals: SUS316L HiMo, Inconel, Hastelloy C-276 and titanium for process, plating and semiconductor equipment.

High-strength fasteners in Grade 5 titanium, SUS316L, chrome-molybdenum steel, aluminium and RENY plastic that let designers downsize while keeping fastening strength.
Stainless steel (including 316L) and chemical-resistant grades are preferred because they resist corrosion, cleaning agents and repeated wash-down while remaining hygienic and easy to clean.
Yes. Stainless steel coupling types are designed to withstand moisture, cleaning chemicals and frequent wash-down cycles common in food and packaging lines.
