M2.5 Button Head Hex Screws, 12.9 Grade Steel (10pcs)

M2.5 button head screws in 12.9-grade steel with a hex socket drive, sold in bags of 10 in a single length — 6 or 8 mm. M2.5 is the mounting thread on Raspberry Pi boards and many other single-board computers, and these also suit frames, mounts and accessories specified for M2.5 hardware.

Key features

• 12.9 is the highest strength class for metric steel screws, so these resist stretching and snapping when tightened firmly
• Button head gives a lower profile than a socket cap head
• Hex socket drive for a hex key or driver

Specifications

• Thread: M2.5 metric
• Head: button head, hex socket
• Material: 12.9-grade alloy steel
• Lengths: 6 mm or 8 mm, measured from under the head to the tip
• Pack: 10 screws of one length

Check the thread before ordering: M2.5 will not fit M2 or M3 holes. 12.9 alloy steel is not stainless, so keep the hardware dry, and use a medium-strength threadlocker on screws that go into metal and see vibration.
