Conveyor belt fasteners join the two ends of a belt without a vulcanising press. A row of steel teeth is driven or bolted into each end and linked by a hinge pin. They suit light and medium belts, temporary repairs and sites where a hot splice is not practical. ConveyorBelting.co.za is a free quote-request service, not a supplier. Tell us the belt width, thickness and duty, and we pass your request to independent suppliers of conveyor belt clips and clamps, who quote you directly with no obligation.

Types of conveyor belt fasteners

Mechanical splices fall into a few common groups:

  • Plate fasteners: steel plates bolted or riveted through the belt, used on thicker rubber belts
  • Hinged clips: staples or teeth driven into the carcass and joined with a pin, common on light textile belts
  • Solid-plate and heavy-duty clamps: for abrasive, high-tension runs where a cold or hot splice is not possible

Pin material matters too. Stainless, galvanised and plain steel pins suit different environments, from wet washdown to dry stockpiles.

Choosing the right belt lacing

Belt lacing must match the belt, not just the width. Check the belt thickness, ply rating and cover grade, the working tension, the smallest pulley diameter and the material carried. Fasteners should be rated for the belt tension, and pulleys must be large enough for the splice to bend without cracking the teeth. Use the maker's table for the mechanical splices you are considering and leave a margin for peak loads. Sharp or sticky material can catch on a raised fastener, so a cleaner or scraper may need a clearance check.

Fasteners compared with vulcanised splices

A mechanical joint is quick, needs no heat or curing time, and can be made by a trained fitter on site. The trade-off is strength and life. A fastener splice usually carries less tension than a hot vulcanised splice and can wear belt cleaners and pulley lagging. It also leaves a gap that can leak fines. Many sites use fasteners for emergencies and temporary repairs, then replace them with a vulcanised joint at the next planned stop. Steel-cord belts are almost always vulcanised.

Fitting and inspection

A good fastener splice starts with a square cut and a belt end free of damaged plies. Use the correct tools, set the fasteners to the right depth and keep the joint straight and square to the belt edge. Lock out the conveyor before any work. Inspect the pin, teeth and belt edge regularly, as a loose pin or a pulled tooth can fail suddenly. Keep a record of when the splice was made.

Comparing conveyor belt fasteners quotes

Prices change with rubber and steel costs, the exchange rate and stock levels. When quotes arrive, check:

  • Exact specification: width, carcass and strength, cover grade and thickness, or the part number, size and standard.
  • Quantity and units: per metre, per roll, per item or per set, and any minimum order or cutting charge.
  • Lead time: ex stock, or imported or made to order, and how long that takes.
  • Delivery and VAT: transport to site, offloading of heavy rolls, whether VAT is included and how long the price holds.

What to include in your request

  • Belt width, thickness and ply or cord rating
  • Working tension and smallest pulley diameter
  • Material carried and operating environment
  • Number of splices and whether tools are needed
  • Delivery address and how soon you need them

Frequently asked questions

Are you a supplier of conveyor belt fasteners?
No. ConveyorBelting.co.za is a free quote-request service. We pass your request to independent suppliers of fasteners and splicing contractors, who quote you directly. There is no charge for the request and no obligation to accept any quote.
What belt details do I need for a quote?
Give the belt width, thickness, ply or cord rating, cover type and working tension if known. Add the smallest pulley diameter, the material carried and whether the belt is rubber or PVC. A photo of the existing splice helps a supplier match the correct fastener.
Can fasteners be used on steel-cord belts?
Generally no. Steel-cord belts carry high tension and are normally joined by hot vulcanising. Mechanical fasteners suit light to medium textile belts. If you are unsure, ask the supplier or a splicing contractor to confirm the belt construction before choosing a joint.
How long does a mechanical splice last?
It depends on belt tension, pulley size, material abrasiveness and how well the splice was fitted and inspected. Many sites treat fasteners as a short-term or backup joint and plan a vulcanised splice for the long term. Ask suppliers for guidance on your specific duty.
