Why fastener kitting matters on real sites
On paper, fasteners are a small line item.
On site, they decide whether work flows or stops.
When mixed cartons of M10 and M12 bolts arrive loose and unlabelled, installers stop installing and start sorting.
Hours are lost.
Mistakes happen.
Wrong bolts get used.
All because fasteners were not kitted properly.
What fastener kitting actually means
Fastener kitting is the practice of:
- Packing bolts, nuts, and washers together per joint
- Labelling by size and location
- Packing as per BOQ or drawing reference
- Sending site-ready kits instead of bulk cartons
This turns fasteners into ready-to-use assemblies.
Why mixed cartons happen
- 1. Bulk packing mentality
Suppliers ship loose parts to save time.
- 2. No BOQ mapping
Packing is not aligned to drawings.
- 3. Warehouse mixing
Different sizes get mixed in storage.
- 3. No site perspective
Packing teams never see installation reality.
How this hurts the project
- Crew idle time
- Installation delays
- Wrong fastener usage
- Rework and inspection failures
- Higher labor cost
What proper kitting fixes
- Zero sorting time
- Correct fasteners at point of use
- Faster installation
- Fewer mistakes
- Better accountability
How to specify fastener kitting
Mention kitting in RFQ
Link kits to BOQ line items
Ask for labelled cartons
Ask for kit list before dispatch
Reject loose mixed cartons
Final thought
Fasteners should arrive ready to install, not ready to sort.
Fastener kitting turns a supply problem into a productivity advantage.
