For an M12 x 1.5 x 100mm fastener, check the thread pitch before choosing: M12 x 1.5 is a fine metric thread, while M12 x 1.75 is a different, coarser thread and is not interchangeable. The Materro zinc-plated Class 8.8 screw is the closest conventional bolt match. The uxcell rods suit applications needing full threads, and the titanium listing specifies the right pitch but offers different head styles. The two M12 x 1.75 flanged options are included for comparison, not as direct replacements.
| Product | Listed pitch | Best suited for |
|---|---|---|
| Materro hex cap screw | 1.5 mm | Partially threaded steel bolt applications |
| uxcell threaded rods | 1.5 mm | Full-thread fastening or stud applications |
| Titanium screw | 1.5 mm | Buyers seeking a titanium fastener and listed head options |
| Flanged hex bolts, 4-piece | 1.75 mm | Coarse-thread applications only |
| YIIFLY flanged bolts | 1.75 mm | Coarse-thread applications only |
Materro Class 8.8 Zinc-Plated Hex Cap Screw
Best for: Buyers who need a conventional, partially threaded M12 x 1.5 x 100mm steel fastener. Its listed 1.50mm pitch matches the requested size, and the product is identified as a Class 8.8 hex head cap screw with a zinc-plated finish.
The listing specifies a 30mm minimum thread length, 19mm head width, and DIN 960 standard. It also states tensile strength of 116,000 psi and proof load of 85,000 psi. The package is listed as five screws.
Limitation: The zinc-plated steel finish is not the same material or corrosion profile as stainless steel. Check whether the finish and partially threaded shank suit the installation environment.
uxcell M12 x 1.5 Stainless Threaded Rods
Best for: Projects that need a 100mm M12 x 1.5 threaded rod rather than a headed bolt. The listing describes two 100mm-long rods made from 304 stainless steel, with fully formed metric fine threads and a 1.5mm pitch.
Full-length threading can suit connections requiring engagement along the rod, such as fastening with nuts or threaded components. The listed material provides a useful alternative to the zinc-plated steel screw when stainless construction is preferred.
Limitation: These are rods or studs, not hex head bolts. Choose another product if the assembly requires an integrated bolt head.
M12 x 1.5 Titanium Screw With Head Options
Best for: Buyers comparing titanium fasteners that list the requested M12 x 1.5 thread pitch and 100mm length. The product name describes socket cap and hex flange head options; listed dimensions include an 8mm socket cap size and 16mm hex size.
This option is distinct from the steel cap screw because the listing identifies titanium. Confirm the exact head style and included configuration before ordering, since the title mentions more than one head type.
Limitation: The provided feature details are limited. They do not specify a strength grade, finish, or thread length, so verify those requirements independently if they matter for the application.
M12 x 1.75 Grade 10.9 Flanged Hex Bolts
Best for: Buyers whose project specifically calls for an M12 x 1.75 coarse-thread flanged bolt, not an M12 x 1.5 bolt. The listing describes four partially threaded alloy-steel bolts with a Grade 10.9 designation and black oxide finish.
The flanged head has serrations below it, which the listing says help distribute load and resist loosening. It names uses across mechanical applications, including appliances, vehicles, furniture, and equipment.
Limitation: The 1.75mm pitch does not match an M12 x 1.5 threaded hole or nut. Do not substitute it just because both fasteners are M12 and 100mm long.
YIIFLY M12 x 1.75 Flanged Hex Bolts
Best for: Projects requiring M12 x 1.75 flanged bolts in a three-piece package. The listing identifies Grade 10.9 alloy steel, a black zinc finish, and serrations intended to grip the material and provide mild vibration resistance.
This is a useful comparison when the required thread is coarse and the assembly benefits from a flanged head. The product title gives a 100mm overall length, while the feature text describes a 100mm thread length; confirm the dimension with the seller if exact usable length is critical.
Limitation: Its listed 1.75mm pitch makes it unsuitable as a direct M12 x 1.5 replacement.
Buying Guide: How to Choose an M12 x 1.5 x 100mm Fastener
Does M12 x 1.5 mean the same as M12 x 1.75?
No. M12 identifies a nominal 12mm thread diameter, while the number after the “x” indicates pitch: the distance between thread peaks. M12 x 1.5 is fine pitch, and M12 x 1.75 is coarse pitch. Use the pitch specified for the mating nut or threaded hole; the two types should not be forced together.
Do you need a bolt, screw, or threaded rod?
Choose a headed screw when the installation needs a hex or socket head. Choose threaded rod when threads along the full 100mm length are required and a separate nut or threaded component will secure it. A partially threaded bolt may provide an unthreaded shank section, so compare the listed thread length with the assembly design.
Which material and finish should you compare?
The listed choices include zinc-plated steel, 304 stainless steel, titanium, and black-finished alloy steel. Match the material and finish to the environment and engineering requirements. Do not assume that a corrosion-resistant finish or a material name alone establishes the fastener’s load capacity.
What dimensions should you verify before ordering?
Confirm pitch, total length, thread length, head shape, and required strength designation. For a replacement, compare the original fastener or a reliable specification. If the listing gives conflicting length details or multiple head styles, resolve the configuration before purchase.
Frequently Asked Questions
What does M12 x 1.5 x 100mm describe?
It describes a nominal 12mm metric thread diameter, a 1.5mm thread pitch, and a 100mm fastener length as stated by the product specification. Verify how the seller measures length for the specific head style.
Can I use an M12 x 1.75 bolt in an M12 x 1.5 hole?
No. The thread pitches differ, so the bolt is not a direct fit. Use the pitch required by the threaded hole or matching nut.
Is the uxcell product a bolt?
No. It is listed as fully threaded rod. It has the requested M12 x 1.5 pitch and 100mm length, but it does not have an integrated bolt head.
Which listed product most closely matches a standard M12 x 1.5 bolt?
The Materro zinc-plated Class 8.8 hex head cap screw is the closest conventional match among these listings because it specifies M12-1.50, 100mm length, a hex head, and partial threading.
