Inner Hexagon Socket Head Screw M4x12

Meet the Inner Hexagon Socket Head Screw M4x12 — a compact, precision-engineered fastener designed for tight spaces and dependable clamping. With an M4 thread and a 12 mm length, this socket head cap screw is the go-to choice when you need a strong, clean connection that sits flush against the surface and stays out of the way during operation.

Key advantages you’ll notice in every project

• 
  Hex drive for controlled torque — the internal hex socket accepts a hex key, delivering precise, repeatable tightening without wobble or slippage. This makes it ideal for assemblies where space is limited and access is tight.
• 
  Low-profile, high-visibility-free head — the socket head design nests neatly into surrounding components, reducing snagging and delivering a streamlined appearance in panels, frames, and enclosures.
• 
  Reliable engagement — the 4 mm nominal thread size provides solid clamping force over a range of thicknesses, helping parts stay aligned even under vibration or regular use.
• 
  Versatile finish options — while the core dimensions stay consistent, this style of screw is commonly available in finishes suited to different environments, from light-duty indoor assemblies to more demanding settings (finish availability varies by supplier).
• 
  Standardized dimensions for easy replacement — M4x12 is a widely used size, so you’ll have no trouble finding compatible nuts, holes, or threaded inserts to pair with it in your project.

Ideal use cases

• 3D printer frames, accessory brackets, and enclosure panels where space between parts is at a premium.
• Electronics housings and inside-component assemblies that require a clean, unobtrusive fastener with a secure hold.
• Bicycle, RC models, and hobby projects where compact, precise fasteners keep moving parts aligned and functioning smoothly.
• Furniture and cabinetry where a neat appearance matters and hardware should stay hidden from view.

How to get the best results

• Use an appropriately sized hex key for snug, controlled tightening. Avoid over-torquing to prevent thread damage or deformation.
• Pair with a corresponding threaded hole, nut, or insert that matches the M4 thread to ensure optimal strength and alignment.
• Verify hole depth and material thickness before installation to choose the correct screw length for a secure clamp without bottoming out.
• Consider the finish and environment of your project. If corrosion resistance or added hardness is required, select an appropriate finish or material from your supplier’s options.

Why this M4x12 socket head screw stands out
