Missing Spring Washers in Solar Installation: Why It Happens and How EPC Teams Fix It
During a site audit, nothing hurts more than seeing:
“Spring washer missing in multiple bolted joints.”
You double-check drawings.
You verify material grades.
Yet washers are missing.
How?
Because fasteners were packed loosely.
The Common Packing Mistake
In many projects:
• Bolts are packed in one bag
• Nuts in another
• Washers dumped in cartons
• Spring washers counted manually
The assumption is:
“We’ll manage at site.”
Reality says otherwise.
Site teams are under pressure.
Installers are working fast.
Loose stocks lead to:
• Missed washers
• Wrong combinations
• Incomplete joints
Why Missing Spring Washers Is a Serious Problem
Without a spring washer:
- • Bolt tension reduces
• Joint loosens under vibration
• Structure moves under wind load
• Inspection fails
• Warranty becomes questionable
One washer is tiny.
Its absence is huge.
The Permanent Solution: Set Packing
Instead of loose cartons, professional EPC suppliers now demand:
✅ 1 bolt
✅ 1 nut
✅ 2 plain washers
✅ 1 spring washer
All in one sealed pack.
This ensures:
- • Zero missing parts
• Easy installation
• Clean audits
• Faster site work
Why Manual Packing Fails
Because:
• Humans miss parts
• Rechecking slows dispatch
• No traceability of mistakes
• No accountability in packing
• No consistency across cartons
How Rajal Industries Solves This
We deliver:
• Pre-packed fastener kits

Final Word
If your site still receives:
- • mixed cartons
• bulk loose washers
• manual counting
• no verification
It’s not “normal”.
It’s risky.
Upgrade your packing before your next audit writes the same story.
