Theme: Detailed introduction of all wrench types with production and marking.

Content (approx. 370 words):

Jovvi‘s titanium wrench family includes four types – each manufactured from ≥90% Grade 5 Ti, heat-treated to 38–42 HRC, and permanently laser-marked.

• 15° offset jaw (allows access in tight spaces)
• Sizes: 6 mm to 24 mm
• Jaw opening tolerance: +0.05/-0.00 mm (tighter than industry standard)
• Laser mark: Size + “Ti ≥90%” on flat face

• 12-point broached hole (engages fastener at 30° increments)
• Sizes: 6 mm to 24 mm
• Broaching concentricity: Runout <0.05 mm
• Laser mark: Size + “12PT” + batch number

• Open end on one side, box end on the other
• Same size both ends
• Length: Optimized for torque (shorter than steel wrenches due to Ti strength)
• Laser mark: Size + “COMBO” + serial number

• Adjustable range: 1–10 N·m (cryostat and precision work)
• Beam material: Grade 23 Ti (extra-low interstitials for low-temperature toughness)
• Spring: Beryllium copper (non-magnetic, stable spring rate)
• Handle: Anodized aluminum
• Laser marks:
  • N·m scale on beam (permanent, engraved-style)
  • Calibration date: CAL: YYYY-MM-DD
  • “Ti ≥90%” on beam

Production Highlight – Torque Wrench Calibration

Each torque wrench is calibrated at 5 points (1, 3, 5, 7, 9 N·m) using dead weights. Calibration data is recorded and linked to the serial number laser-marked on the tool.

Custom Laser Marking for Torque Wrenches

• Hospital asset number
• Next calibration due date (customer-calculated)
• Department name (e.g., “CRYOGEN ONLY”)

Wrench Set Packaging

All wrenches are stored in foam-lined ABS case with individual cutouts. Each cutout is labeled with the laser-marked size for easy return.

Factory note: “Our wrenches are not forged and then coated – they are solid titanium from end to end. The laser mark proves it.”
