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.

• 
  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.

Installation tips

• Pre-drill a clearance hole appropriate for M4 threads to ensure smooth insertion and accurate alignment
