Choosing hardware consumables can be awkward because the category mixes everyday fastener assortments with highly specific instrument parts. The right pick depends less on finding the lowest price and more on matching the consumable to the machine, model, or repair task in front of you.
Quick take
- For a compact RC fastener assortment: the 520pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners Black from RC Lelut is the straightforward black metal kit with M3 and M4 hardware.
- For the largest RC assortment here: the 1000Pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners for Tra gives the broadest stated piece count and includes hex flat and button head screws plus clips, pins, washers, and nuts.
- For the lowest listed price: the 520Pcs Universal RC Screw Kit Screws Assortment Set Hardware Fasteners for Traxx is the least expensive option in the group.
- For a Thermo Scientific instrument consumable: the NEW Thermo Fisher 70111-20972 Ion Transfer Tube 500-Micron Capillary TSQ Quantum is a very different purchase: a model-specific ion transfer tube rather than a general fastener kit.

Concise product notes
520pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners Black
This RC Lelut kit is the neat middle ground among the RC-focused choices: it is a black metal assortment with M3 and M4 flat head and round head screws, washers, lock nuts, O-circle, pins, R clips, and E-clips. The description calls out compatibility with multiple RC brands and scale categories, which makes it a practical bench box for crawler, truck, buggy, and car maintenance. The main limitation is count: it is a 520-piece kit, so shoppers who specifically want the largest assortment in this group will naturally compare it with the 1000-piece kit instead.
1000Pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners for Tra
The 1000-piece RC kit is the broadest fastener assortment in this comparison. It is built around M3 and M4 hardware, with hex flat and button head screws, bolt washers, lock nuts, shell clips, E-clips, pins, and O-circle pieces. The transparent case and divided-grid organization are useful if you want common RC fasteners separated rather than loose in a single bin. Its limitation is specificity: the color is described as silver or another metallic shade, and the product title is truncated after "for Tra," so shoppers focused on a clean black kit or a fully spelled-out title may prefer one of the 520-piece alternatives.
520Pcs Universal RC Screw Kit Screws Assortment Set Hardware Fasteners for Traxx
This is the lowest-priced hardware consumable here and still covers the core RC assortment idea: black metal M3 and M4 screws in flat and round head styles, plus washers, lock nuts, O-circle, pins, R clips, and E-clips. It also lists a 3 millimeter compatible groove diameter and a lubricated finish type, giving it a slightly different attribute profile from the other 520-piece option. The tradeoff is that the title is cut off at "Traxx," and it does not show the RC Lelut brand name that appears with the similarly sized black kit.
NEW Thermo Fisher 70111-20972 Ion Transfer Tube 500-Micron Capillary TSQ Quantum
This Thermo Scientific part sits in a different category of need than the RC screw assortments. It is an ion transfer tube, also described as a 500-micron capillary, with model number 70111-20972 and an intended use tied to the Thermo TSQ Quantum Access Max Triple Quadrupole Spectrometer. Choose it only when that specific instrument consumable is the job, not when you are shopping for general workshop hardware. The limitation is equally clear: at the top of the price range, it is far more expensive than the RC fastener kits and is not a general-purpose screw assortment.
Final recommendation
If you are maintaining RC vehicles and want the most hardware in one box, the 1000Pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners for Tra is the strongest fit because it has the largest stated assortment and includes hex flat and button head M3 and M4 hardware.
If the lowest listed price matters more than piece count, choose the 520Pcs Universal RC Screw Kit Screws Assortment Set Hardware Fasteners for Traxx at USD 13.90. It covers the same general RC screw-kit role while staying at the bottom of the group's price range.
If you prefer the named RC Lelut black kit, the 520pcs Universal RC Screw Kit Screws Assortment Set, Hardware Fasteners Black is the cleaner pick among the two 520-piece black assortments because the title and attributes identify RC Lelut and black metal hardware.
For Thermo Scientific lab instrument maintenance, the only relevant choice here is the NEW Thermo Fisher 70111-20972 Ion Transfer Tube 500-Micron Capillary TSQ Quantum. Its 500-micron capillary description and TSQ Quantum Access Max intended use put it outside the RC hardware comparison entirely.
