Mellewell M6-1.0 x 16mm Flanged Button Head Socket Cap Screw Bolts, Allen Socket Drive, Stainless Steel 304, Black Finish, Quantity 25: desertcart.com: Industrial & Scientific

Review: Good replacement hardware with a clean finish - These bolts matched the M6-1.0 thread and 12-millimeter length needed for the project. The flanged button heads create a finished appearance and spread the load over a slightly larger surface than a standard socket-head screw. The black finish coordinated well with the existing equipment and hardware. The Allen sockets engaged properly, and having twenty-five bolts in the package provided useful extras.
Review: Take off your hex heads - Very nice....no washer needed with these. Perfect for motorcycles with black fasteners.

## Questions & Answers

**Q: How is the length measured? Just the threaded part or the entire bolt (head included)?**
A: The length is measured by the length of the shaft of the bolt. From below the head to end of threads.

**Q: Will these get surface rust if used for outside?**
A: Eventually it will rust as does any steel related product. However it should be quite so time before it does. I live in Tennessee and used these fasteners on my lawn furniture which we get rain and humidity and they have not rusted yet.

**Q: The photo of thumbnail is not the flanged button head socket cap screw.  what's wrong?**
A: This is a good place to look them up.

**Q: How long in inches**
A: .4725 inches or just under 1/2” under the head.  To get any exact metric to inch conversion multiply the millimeters by .039375

### ⭐⭐⭐⭐⭐ Good replacement hardware with a clean finish
*by D***N on July 12, 2026*

These bolts matched the M6-1.0 thread and 12-millimeter length needed for the project. The flanged button heads create a finished appearance and spread the load over a slightly larger surface than a standard socket-head screw. The black finish coordinated well with the existing equipment and hardware. The Allen sockets engaged properly, and having twenty-five bolts in the package provided useful extras.

### ⭐⭐⭐⭐⭐ Take off your hex heads
*by T***N on July 2, 2026*

Very nice....no washer needed with these. Perfect for motorcycles with black fasteners.

### ⭐⭐⭐⭐⭐ Well specified low-profile M5 hardware in a useful bulk pack
*by M***N on September 2, 2026*

Fasteners are much easier to order correctly when every critical dimension is stated, and this listing provides the useful numbers. These are M5 screws with a 0.8 mm thread pitch and a listed 10 mm length. The flanged button head measures 11.5 mm across and uses a 3 mm Allen key. That wide built-in flange spreads the bearing load over a larger surface and can eliminate the need for a separate washer in many noncritical applications, while the low domed head fits spaces where a taller socket cap would protrude too far. The package contains 50 screws made from 304 stainless steel with a black oxide finish for a darker appearance and added protection against corrosion and tarnishing. Before ordering, confirm the thread pitch as well as the diameter, since an M5 fastener with the wrong pitch can damage the mating threads. Use a fully seated 3 mm hex key and avoid excessive torque because a shallow button-head socket offers less tool engagement than a tall cap screw. Overall, this is a well-specified, versatile bulk pack for projects that need a clean, low-profile metric fastener.
