Flexco FAQ from a Parts Buyer Who Has Made the Mistakes

I'm the office administrator for a 45-person industrial maintenance company. I manage all conveyor parts purchasing—roughly $300,000 a year across 9 vendors. Maybe $280,000; I'd have to check our 2024 totals. I report to operations and finance, so I'm the one who gets called when a Flexco order doesn't fit. This article answers the questions our mechanics ask, plus the questions I wish I had asked in my first year.

These answers come from our operation: a fixed limestone handling site with standard 36-inch and 48-inch belts. If you're a mobile contractor or have unusual conveyor geometry, check with your distributor. I'll flag context where it matters.

1. What's the difference between Flexco fastener sizes?

Start with belt thickness and pulley diameter, not with "bigger is stronger." A staple-style fastener like the Alligator line works for thin to medium belts. A bolted plate fastener is usually for thicker, higher-tension belts. But the exact size has to match the belt so the splice can pass over the pulleys.

The mistake I see: someone chooses a heavier fastener because they assume it will "do more." It doesn't. If the splice can't flex around the pulley, it fails anyway. In 2023, we had a premature splice failure because the part number matched the belt we wanted, not the belt we had. Now the tool room has a gauge and a Flexco spec sheet, and the mechanics know that 5 minutes of measuring beats 5 days of re-splicing.

5 minutes of verification beats 5 days of correction.

2. What is a Flexco stringer mount?

A stringer is the steel rail on each side of a conveyor frame. Many belt cleaner systems attach to that rail, so the bracket is called a stringer mount. If you see "Flexco stringer mount" on an order, it's not part of the fastener—it's the bracket that holds the belt cleaner onto the conveyor structure.

What to check: stringer flange width, bolt-hole spacing, and whether you need a left- or right-hand orientation. We once ordered a stringer mount for the wrong side. Nobody thought to check because the listing looked universal. It wasn't. The restocking fee cost more than the bracket, and we still had a cleaner sitting in the warehouse.

3. How do I know the Flexco part number is right before I order?

Use the old part, not the description. The first time I ordered a belt cleaner blade, I typed in the description from a worn-down part. Turned out there were three variants. We received a blade with the right length but the wrong wear compound. I still kick myself—if I'd read the stamped number on the back, I'd have caught it immediately.

Now the process is simple:

• Photograph the old part and the nameplate.
• Read every stamped, printed, or engraved number.
• Compare against the Flexco spec sheet or the distributor's cross-reference.
• Add a note on the PO describing the final application.

That checklist has saved us an estimated $8,000 in wrong parts and return freight.

4. Should I stock Flexco fasteners in inventory or order as needed?

Prevention over panic. We stock the three fastener sizes that cover 80 percent of the belts at our site. That means our maintenance team rarely waits for a basic repair part. But we don't stock every cleaner blade and compound. Belt cleaner blades are exposed to wear and can harden on a shelf; excess inventory is a different type of waste.

This works for us because we're a fixed site with predictable belt sizes. If you're a contractor who works on different conveyors every week, a small travel kit plus a distributor account makes more sense. Your mileage may vary.

5. Why is a bigger number on a Flexco fastener not always better?

Fastener numbers are dimensional codes, not quality grades. A heavier fastener on a thin belt can damage the carcass; a lighter fastener on a thick belt can pull out. The number needs to match the belt specification, not the tension anxiety.

When a supplier says "heavy duty," ask for data. Per FTC guidelines (ftc.gov), marketing claims like that need to be substantiated. We ask for the test sheet, belt thickness range, and recommended minimum pulley diameter. If it's not in writing, it's not an engineering recommendation.

6. Does installing a Flexco belt fastener take special training?

It takes routine, not magic. Our senior mechanic, Eddie, went through a half-day installation session years ago. Now he runs a 10-point check on the lacing tool before every splice: upper and lower plates, air pressure, staple magazine, belt alignment. He can get a good result from a simple tool, but the checklist is what makes it repeatable.

We also asked for Flexco's installation white paper and keep a copy in the tool room. One more thing: when we bought a powered lacing tool, we looked at a Hercules vs Flexco comparison. Both brands had good reviews. We chose Flexco because the local distributor had the dies in stock and could lend us an emergency tool. The tool mattered less than Eddie's willingness to follow the steps.

7. What hidden costs show up after you order Flexco parts?

Freight, tooling, and time. Heavy splice kits ship freight, not parcel. Rates change often (surprise, surprise). For small sample parts, we sometimes use USPS, but according to USPS (usps.com), rates are adjusted periodically—check current numbers before ordering. For larger parts, get a delivered price before you place the PO, not after.

Also ask about the accessories: belt cutter, skiver, lacing machine, and spare jaws. A fastener is only part of the repair. The first time we ordered a full splice kit, the tooling added about 30 percent to the total cost. That's not a reason to skip it; it's a reason to plan for it.

8. What do I do if a Flexco order arrives but looks wrong?

Don't sign. It sounds obvious, but I've called receiving from the dock and told them to inspect before signing. If the boxes are damaged, write it on the delivery receipt. If the part number is wrong, refuse the shipment and call the distributor before the driver leaves. Once the part is in your warehouse, the return process becomes a negotiation.

We had a box of fastener strips that looked fine from the outside; the labels were correct, but 40 percent of the boxes contained the next shorter length. If we hadn't spot-checked the stamped part numbers on three boxes, that shipment would have gone to a remote site and cost us a day and a half of downtime. Verification is the cheap insurance.
