Techcon M3 stainless steel hex nut dispenser part

Description

Dispenser parts for Techcon fluid dispensing equipment include the fasteners that hold a dispense assembly’s brackets, mounts, and covers together through repeated service cycles. This M3 hex nut, 5.5mm across the flats, is one of those small fastener-level components used during assembly and rebuild work on compatible Techcon equipment.

Dispenser parts specifications

• Thread: M3 (metric)
• Width across flats: 5.5mm
• Style: hex nut
• Material: stainless steel
• Manufacturer: Techcon (OK International / Dover)

Stainless steel is the standard material choice for fastener-level dispenser parts because a dispense station is a wash-down and chemical-exposure environment. Adhesive overspray, solvent cleaning, and general shop humidity all accelerate corrosion on a plain steel fastener, and a corroded nut is far more likely to round off or seize during a later service call. Stainless construction keeps small hardware serviceable over the equipment’s working life instead of becoming a source of stripped threads and stuck fasteners.

Dispenser parts fitment

An M3 nut is a common size across many Techcon assemblies, brackets, and mounting plates, so confirm the exact thread engagement and mating bolt length called out in your equipment’s service documentation before a rebuild. Reusing a nut with worn or previously over-torqued threads is a common cause of a bracket working loose under vibration. When in doubt, replace the nut and its mating fastener as a pair rather than mixing a new nut with a worn bolt, particularly on brackets that see repeated removal during routine servicing.

Tighten to a snug fit appropriate for M3 hardware. Over-torquing a small fastener like this is a common way to strip the thread or crack a thin mounting bracket, while under-torquing leaves the joint free to back off under the vibration a dispense station sees during normal cycling. A small dab of removable thread locker is worth considering on brackets that see continuous vibration but are not routinely disassembled.

Ordering notes

Stock this nut alongside other dispensers, mixers, and nozzles service hardware so a routine bracket repair does not stall waiting on a single fastener. For manufacturer platform context, see Techcon’s fluid dispensing systems.
