Choosing hardware consumables gets tricky because the category can mean very different things: a box of RC fasteners, a machine-tool tapping chuck set, or even reference literature for small parts. The right pick depends less on the category name and more on whether you need physical fasteners, a tapping setup, or catalog information for older vehicle parts.
Quick take
- For a low-cost RC fastener assortment: the 520Pcs Universal RC Screw Kit Screws Assortment Set Hardware Fasteners for Traxx is the lowest-listed choice and focuses on M3 and M4 RC maintenance pieces.
- For a larger RC screw assortment: the 1000Pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners for Tra gives you a bigger kit format with a transparent storage box and RC model compatibility language.
- For tapping work on a drilling machine: the Fast Change Tapping Chuck Set Drill Tap Tool Holder Hardware Consumables is the specialized tool-holder option, with multiple tap chucks included.
- For parts-reference literature: the Unipart Catalog HARDWARE AND CONSUMABLES Small and Consumables MMM1171 is a used English-language November 1982 catalog rather than a box of fasteners or tooling.
Listed price comparison
The listed prices span USD 13.90 to USD 86.28, with the lowest price 84% below the highest. That spread matters because the four choices are not interchangeable: two are RC screw assortments, one is a tapping chuck set, and one is catalog literature.

Decision matrix
| Need | Closest match | Why it fits | Main tradeoff |
|---|---|---|---|
| RC car repair fasteners at the lowest listed price | 520Pcs Universal RC Screw Kit Screws Assortment Set Hardware Fasteners for Traxx | Includes M3 and M4 screws, washers, lock nuts, O-circle, pins, R clips, and E-clips | Smaller assortment than the other RC screw kit |
| More RC hardware pieces in one organizer-style kit | 1000Pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners for Tra | Title and description focus on a larger RC screw kit with a transparent box | Description contains mixed count wording, so choose it for the title-level larger kit concept rather than a perfectly tidy parts statement |
| Tool holding for tapping on a drilling machine | Fast Change Tapping Chuck Set Drill Tap Tool Holder Hardware Consumables | Includes a connecting handle and tap chucks from M3 through M12 | Highest listed price in this group |
| Reference material for older vehicle parts | Unipart Catalog HARDWARE AND CONSUMABLES Small and Consumables MMM1171 | English-language Unipart literature with part-number focus and November 1982 date | Used condition, and it is literature rather than consumable hardware |
Concise product notes
520Pcs Universal RC Screw Kit Screws Assortment Set Hardware Fasteners for Traxx
This is the easiest pick when the job is RC maintenance and the priority is a compact assortment of fasteners. The kit language names compatibility with Traxxas, Axial, Arrma, Redcat, RC4WD, HSP, Exceed RC, Losi, HPI, Himoto, and Tamiya, and it includes M3 and M4 screws plus washers, lock nuts, clips, pins, and O-circles. The black color and lubricated finish are also listed. The limitation is scope: it is an RC-focused screw kit with a 3 millimeter listed item diameter, so it is not a general household hardware bin or a drilling-machine accessory.
1000Pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners for Tra
Pick this one if you want the larger RC screw-kit format and like the idea of pieces divided into a transparent box for organization. The title points to a 1000-piece universal RC screw assortment, and the description mentions flat head and round head M3 and M4 screws, washers, lock nuts, body clips, E-clips, pins, and O-circles for RC cars, crawlers, trucks, and buggies. A limitation is that the description also includes mixed wording around package quantity, so the clearest reason to choose it is the broader RC assortment role rather than a single neatly stated parts count.
Fast Change Tapping Chuck Set Drill Tap Tool Holder Hardware Consumables
This set is the specialty choice for shoppers who are not looking for loose screws at all, but for a drill tap tool holder arrangement. It names a fast change tapping chuck set, a connecting handle, and tap chucks for M3, M4, M5, M6-8, M10, and M12, with alloy material and drilling-machine use in the description. That makes it the most task-specific item in the group. The drawback is cost and relevance: at the top of the listed range, it only makes sense if the tapping chuck function is what you actually need.
Unipart Catalog HARDWARE AND CONSUMABLES Small and Consumables MMM1171
The Unipart catalog belongs on a different shopping shortlist than the physical hardware kits. Choose it when your goal is reference material: it is listed as original literature, in English, with part number MMM1171 and a November 1982 date. The description connects it to hardware and consumables information and part numbers for older vehicle contexts. Its limitation is built into the product type and condition: it is a used catalog, not a box of replacement fasteners, not a tool holder, and not a modern mixed hardware assortment.
How to choose among these hardware consumables
Start by separating the four into three use cases. If you are servicing RC models, the two screw kits are the relevant comparison. If you are setting up tapping work on a drilling machine, the tapping chuck set is the only product here that matches that role. If you need old parts information, the Unipart catalog is the only literature item.
For RC shoppers, the decision is mainly about assortment size and presentation. The 520-piece kit is the lowest-listed item and includes a broad mix of small RC fasteners and clips. It is a straightforward way to cover M3 and M4 RC screw needs without moving into the higher listed prices. The larger RC kit is priced above it and adds a bigger title-level assortment concept with a storage-box emphasis. If you often want more spare RC pieces on hand, that larger kit may be the more convenient match.
For workshop shoppers, the tapping chuck set sits apart. The included tap chuck range from M3 to M12 and the drill tap tool holder wording make it a more focused tool-accessory purchase than a replenishment pack. Its listed price is also the highest, so it should be reserved for shoppers who specifically need that tapping setup rather than general fastener supply.
For catalog shoppers, the Unipart item is about information rather than installation. The used condition, English language, original designation, and MMM1171 part number are the practical signals. It is not competing with the RC kits on piece count, and it is not competing with the tapping chuck set on machine-tool function.
Final recommendation
For most shoppers looking at hardware consumables in the everyday sense of small replacement pieces, the 520Pcs Universal RC Screw Kit Screws Assortment Set Hardware Fasteners for Traxx is the cleanest starting point at USD 13.90, especially because it includes M3 and M4 screws plus related RC clips, pins, washers, and lock nuts. Move up to the 1000Pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners for Tra if the larger RC assortment title and organizer-style description are more appealing.
Choose the Fast Change Tapping Chuck Set Drill Tap Tool Holder Hardware Consumables only when the tap-holder function is the requirement, because its USD 86.28 listed price sits at the top of the range. Choose the Unipart Catalog HARDWARE AND CONSUMABLES Small and Consumables MMM1171 when part-number literature is the actual target, since its used November 1982 catalog format is a separate need from buying consumable fasteners.
