Client Background
A Canadian manufacturer of high‑speed rotary canning machines (up to 1200 cans/minute) needed quick‑release knurled nuts and bolt series for their change parts (guide rails, starwheels, and can handling components). Each product changeover required operators to loosen and tighten dozens of standard nuts, causing significant downtime.
Challenge
The client wanted custom non-standard fasteners with a hand‑knurled body for tool‑less operation, but also needed high wear resistance (since change parts are swapped 2–3 times per shift). The nut material had to resist corrosion from wet canning environments (temperature cycling, steam, and acidic beverages like cola).
Our Solution
Custom Design: Produced knurled nut bolts with a knurled head for hand tightening and a nylon locking patch to prevent vibration loosening. The thread size was non‑standard (M16x1.5 left‑hand thread) as per client’s specification.
Material: Manufactured from 304 stainless steel with enhanced surface hardness (via work hardening). Meets RoHS and food‑contact safety requirements.
Quality Control: 100% thread gauge inspection and hardness test (HRC 28–32). CE certified and compliant with ISO9001.
Prototype & Delivery: First 7‑day prototype confirmed ergonomics and fit. Full order of 5,000 pieces was shipped in 10 days (from stock of raw material).
Result
Changeover time reduced from 45 minutes to 12 minutes per product switch.
Operator hand fatigue decreased due to knurled design.
The Canadian client increased their own machine output by 18% due to faster changeovers.
Repeat orders doubled in 6 months, including OEM/ODM requests for other non-standard fasteners like hex socket screws and machine screws.
