Everything for the repair in one box.
Some jobs need a set, not a single part. Retmay carries thread repair kits and refills in inch and metric sizes, O-ring and retaining ring kits, drill assortments, arbor kits and mounting hardware kits, each packed so the pieces for the job arrive together.
Why it matters
A kit saves the second trip.
A stripped thread is the classic case. The repair takes a tap, an insertion tool and the insert itself, all in matching sizes, and often a drill. A thread repair kit puts them in one box, and refill packs restock the inserts once the tools are on hand.
Assortments work the same way for common wear parts. An O-ring kit or an internal and external retaining ring kit holds a spread of sizes, so the right one is there when a part comes apart.
For mounting and assembly, hardware kits group the brackets, bolts and fittings a specific job calls for, so nothing is missing at install.

Questions
Assortments & Kits FAQs
What is in a thread repair kit?
A complete kit includes the tap, insertion tool and inserts for one thread size, and some include the drill. Refill packs contain inserts only.
Do you carry metric thread repair?
Yes. Kits and refills are listed in both inch sizes and metric sizes from M5 and up.
What is the difference between an assortment and a Professional Kit?
Assortments are manufacturer kits for a repair or part family. Professional Kits are Retmay trays of fasteners and fittings built for a trade, priced as a kit.
Can you build a custom kit?
Yes. Send the parts and quantities and we will quote a kit, labeled and packed the way your crew uses it.
