TNHO Lock Hex Nuts for Industrial Fastening
Our hex nut series includes standard hex nuts, thin nuts, staked lock nuts and nylon insert lock nuts. Made of...
Our washers includes flat plain washers and inner serrated toothed lock washers in mainstream M6 standard size, made of stainless steel and zinc-plated carbon steel. Plain washers evenly disperse fastening pressure to avoid surface crushing; inner toothed washers bite tightly into contact surface for anti-loosening and conductive grounding. These accessories perfectly match all kinds of meter screws and bolts, widely used on electric meter shell, terminal block and internal component assembly for anti-vibration and stable wiring connection.

1.Two differentiated structural washer design for dual usage: Plain washer for pressure dispersion protection and inner tooth washer for anti-loose & grounding to meet two core assembly demands of meter production.
2.Two optional anti-corrosion raw material selections: Stainless steel adapts humid outdoor environment while zinc-plated steel lowers cost for conventional indoor meter bulk assembly projects.
3.Precision stamping uniform dimensional consistency: Accurate stamping processing controls inner hole & outer circle tolerance to perfectly fit corresponding metric bolt outer diameter without assembly gap.
4.Inner sharp serration anti-slip locking structure: Dense inner tooth bites into fitting surfaces to boost friction and stop bolt loosening under long-term meter operating vibration.
5.Full customizable dimensional parameter service: Apart from standard M6 size, we tailor ID, OD and thickness to match special non-standard meter screw and terminal structure.
Effective protection for meter sheet & plastic casing
Plain washer disperses bolt tightening pressure to avoid workpiece surface dent and crack during component locking installation.
Reliable anti-loose & grounding for terminal wiring
Inner serrated washer realizes dual functions of vibration-proof fastening and conductive earthing to reduce terminal overheating failure risk.
Excellent all-weather rust resistant surface treatment
Zinc plating and stainless steel passivation prevent rust erosion inside damp closed meter cabinet all year round.
Ready spot inventory of mainstream M6 standard specification
In-stock common M6 washers can deliver small sample orders and customers’ urgent bulk purchase rapidly.
Wide universal matching compatibility for meter fasteners
Perfectly compatible with our self-produced all types of screws, bolts and studs to realize one-stop supporting procurement.
Strict finished edge deburring processing quality control
Smooth burr-free washer edge avoids scratching meter coating, PCB copper foil and terminal wire insulation during assembly.
