The best motorcycle nuts and bolts depend on the repair: a mixed assortment suits general shop tasks, a battery-terminal kit is made for battery connections, and a fairing kit covers common bodywork fasteners. The 680-piece smseace kit adds lock washers, while the 72-piece Fixpax set offers M5 and M6 battery hardware. Check thread diameter and length against the motorcycle’s original fastener before buying.

smseace 680-Piece Nuts And Bolts Assortment
Best for: Riders or home mechanics who want a broad selection of general-purpose hardware for motorcycle repairs, machinery, or furniture. It was selected as the most comprehensive mixed assortment in this list.
The kit contains 680 pieces across 27 listed sizes: 13 screw sizes, four nut sizes, four flat-washer sizes, and four lock-washer sizes. The manufacturer describes the hardware as carbon steel and notes smooth, clean threads designed for easier installation and resistance to slipping or deformation.
Limitation: This is a general assortment, not a motorcycle-specific fitment kit. Confirm the thread and length required for each repair before use.
smseace 516-Piece Black Hardware Kit
Best for: Buyers seeking a smaller black-hardware assortment for routine workshop tasks. Choose this if a selection of screws, nuts, and flat washers is more useful than the additional lock washers in the 680-piece kit.
The 516-piece kit includes 13 screw sizes, four nut sizes, and four flat-washer sizes in M3, M4, M5, and M6 ranges. Its listed material is carbon steel, with the manufacturer describing corrosion resistance and clean, precision-rolled threads. It is presented for machinery, furniture, automotive, and motorcycle repairs.
Limitation: The listed contents do not include lock washers. The assortment also does not specify motorcycle model fitment, so match the hardware to the original fastener.
Fixpax 72-Piece Motorcycle Battery Terminal Kit
Best for: Motorcycle owners replacing battery-terminal fasteners who need both M5 and M6 options. It was selected because the kit is specifically organized around battery connections rather than general repairs.
The 72 pieces include six bolts each in M5 × 10, 12, and 14 mm and M6 × 12, 16, and 20 mm, plus 18 rectangular anti-rotation nuts for each thread size. The manufacturer lists 304 stainless steel and describes the hardware as rust- and corrosion-resistant.
Limitation: Having both sizes does not guarantee fitment. Check the battery terminal’s thread size and required bolt length; do not force a fastener that does not thread correctly.
Tnuocke 230-Piece Motorcycle Fairing Bolt Kit
Best for: Riders replacing fairing, windscreen, or body-panel hardware. This kit was selected for its mix of M5 and M6 bolts, clips, washers, rubber nuts, and self-tapping screws.
Its listed contents include several bolt lengths, fastening nuts, M5 self-tapping screws, rubber nuts, nylon washers, plastic pillars, fairing clips, and two wrenches. The product describes its hardware as stainless steel with a black zinc surface finish and says the included hexagonal wrench is intended to help reach narrow installation spaces.
Limitation: The product’s broad fitment language does not establish compatibility with every motorcycle. Compare the original fastener type, size, and panel requirements before ordering.
Six-Piece M6 Motorcycle Battery Bolt Kit
Best for: A repair that specifically calls for M6 × 16 mm battery bolts. This compact kit is a more focused choice than the Fixpax assortment when the required dimensions are already known.
The six-piece set uses carbon steel and includes M6 coarse-thread bolts with a stated 1.0 mm pitch, 16 mm screw length, and 10 mm hex-head spanner size. Its square nuts measure 11 × 8 × 4 mm.
Limitation: It offers only the listed M6 × 16 mm configuration. Avoid choosing it if the motorcycle requires M5 hardware or a different bolt length.
Buying Guide: Choosing Motorcycle Nuts And Bolts
Which type of kit fits the repair?
For mixed workshop jobs, choose an assortment such as the smseace 680-piece or 516-piece kit. For battery terminals, compare the required thread size and length with the Fixpax range or the dedicated M6 set. For body panels, the Tnuocke kit is the most specialized option because it includes fairing clips and panel-related pieces.
How do you check fastener size?
Use the removed fastener or the motorcycle’s service information to confirm diameter, thread pitch, length, and head style. M5 and M6 are different thread diameters, and a bolt that appears close in size can still be unsuitable. Check the matching nut or mounting point as well.
Should you choose stainless steel or carbon steel?
The battery-terminal set lists 304 stainless steel, while both smseace assortments and the six-piece M6 kit list carbon steel. The fairing kit describes stainless steel with a black zinc surface. Compare the material and finish with the repair’s needs, and do not assume that a finish alone confirms suitability for every location.
When are washers and clips important?
Washers can be part of the original assembly and should not be omitted when required. The 680-piece assortment includes flat and lock washers; the fairing kit lists nylon washers and several clip types. Match replacement components to the original setup rather than substituting parts solely because they are included in a kit.
Frequently Asked Questions
Are M5 and M6 motorcycle bolts interchangeable?
No. They have different thread diameters. Use the size specified for the battery, panel, or mounting point.
Which kit is best for battery terminals?
The Fixpax kit is the broadest battery-focused option here because it includes multiple M5 and M6 bolt lengths. The six-piece set is for repairs specifically requiring M6 × 16 mm hardware.
Can a general nuts-and-bolts assortment fit every motorcycle?
No. General assortments provide multiple sizes but do not establish model-specific compatibility. Verify the original fastener dimensions before installation.
Does the fairing kit include clips as well as bolts?
Yes. Its listed contents include M6, M7, and M8 fairing clips, along with M5 and M6 bolts, washers, pillars, and other fasteners.
