Mechanical fasteners allow conveyor belt joints to be made quickly in the field, without the need for a vulcanizing press or complex tools. They are the ideal solution for urgent repairs, temporary splices and applications where intervention speed is more critical than maximum joint strength.
At NFP Industrial we supply belt fasteners from Kunming Conveyor Belt Co., Ltd., available in three types depending on the belt thickness and application.
Types of fasteners available
HK Fasteners (Hook Fasteners)
Hook fasteners for lightweight PVC and PU belts. Quick manual installation without special tools. Ideal for joints in low-thickness belts on packaging, logistics and general handling lines.
MRS Fasteners (MRS Fasteners)
Screw fasteners for medium-thickness belts. Greater strength than HK. Suitable for multi-ply PVC belts and belts with higher working tension. Installation with standard manual tool.
HG Fasteners (High Frequency Fasteners)
High-frequency welded fasteners. More resistant joint than conventional mechanical fasteners. For belts requiring a more durable joint without resorting to hot vulcanization.
When to use mechanical fasteners instead of vulcanization?
| Situation | Recommended solution |
|---|---|
| Urgent field repair (line stopped) | HK or MRS mechanical fasteners |
| Temporary splice while waiting for the press | Mechanical fasteners |
| Lightweight PVC/PU belt in packaging or logistics | HK fasteners |
| Medium-thickness belt with moderate tension | MRS fasteners |
| Durable joint without vulcanizing press | HG fasteners (high frequency) |
| Maximum splice strength (>90%) | Splicing press or hot vulcanization |
