Meet the Hexagon Socket Countersunk Head Carbon Steel Screws M4x12 — a precision fastener built for flush, secure assemblies. With a low-profile countersunk head and an internal hex drive, these screws combine a clean finish with dependable torque control for a wide range of projects.

Why this screw stands out

• Flush, professional finish — countersunk head sits level with the surface, reducing snag points and creating a sleek look on cabinets, enclosures, and metalwork.
• Hex socket drive — internal Allen drive minimizes cam-out and allows accurate, repeatable tightening with common hex keys or drivers.
• Reliable carbon steel construction — sturdy, versatile fasteners suitable for everyday fastening tasks in workshops and on-site jobs.
• Precise metric sizing — M4 diameter with a 12 mm length, designed to fit standard metric threading and a variety of materials.
• Compact for small assemblies — the 4x12 profile is ideal for lightweight electronics housings, furniture fixtures, and thin-gauge metal or wood applications.

Ideal use cases

• Cabinetmaking and furniture assembly where a flush, unobtrusive fastener is desired
• Electronic enclosures and equipment housings to maintain a clean exterior surface
• Light metalwork, aluminum profiles, and sheet-metal projects requiring dependable, non-protruding joints

Installation tips

• Pre-drill a clearance hole appropriate for M4 threads to ensure smooth insertion and accurate alignment
• Use a high-torque hex key to achieve full seating without stripping the hex socket
• Aim for a snug, but not over-tightened, finish to preserve material integrity and seating depth
