Mellewell M6-1.0 x 16mm Flanged Button Head Socket Cap Screw Bolts, Allen Socket Drive, Stainless Steel 304, Black Finish, Quantity 25

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.

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

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.

high quality bolts, fit and finish is perfect for my application. Arrived the next day, great price and value for 50 bolts! Fit perfectly.

M8 x 70mm: Overall fasteners had a very high quality look. Threads were properly sized. Judging by the sound of tapping a couple together they were not an overly soft material like many fully threaded fasteners are. The Allen wrench fit perfectly in the head (M8 takes a 5mm Allen wrench). I bought fasteners longer than needed and cut to the exact length I needed with a pre-threaded nut to condition the threads after cut/grind. I had an application which required fully threaded fasteners. The original application had a fastener welded to a plate inside a bumper support. It's not always easy to find long bolts fully threaded unless they are dead soft. When I saw these and they came with a large head it was a rare time when I felt like I found exactly what I needed. The thread stops something like 0.5mm short of the head. That actually ended up helping me as well as it created a narrow gap under the head where the braze material could wick under. I wound a ring of braze material around the threads and compressed it under the head. I then surrounded the head with another ring and heated from beneath. If you needed no gap you could use a washer, which always has a slightly larger hole than the thread size, or the thread could have a slight countersink. Zero complaints.

These screws are as described and decent quality for the price. Be careful when tightening them down, the Allen head can strip out.

Good quality stainless bolts. Worked perfect for new fenders on Jeep.

Nice product

They were what I expected

Bonne qualité pour petits projets

I bought these to replace the fasteners in an adjustable timing gear. The original ones had tall narrow socket heads. These are very low profile with a very broad flange which spreads the load better across the slots. The low profile was required due to the modification of narrowing the gear for a different application .. stainless with consistent threading and socket head sizing
