*USED* Screw M4*12

Discover a dependable, compact fastener built for a variety of small-scale projects: the USED M4x12 screw. With a 4 mm diameter and 12 mm length, this metric screw is a confident choice for electronics enclosures, mounting brackets, and tight-space assemblies where a lower-profile fastener is essential.

Condition: pre-owned. This screw has seen prior use but remains fully functional for standard M4-threaded applications. Expect minor cosmetic wear or tool marks consistent with previous installation. It’s an economical option that delivers the same fit and performance as a new part in everyday projects.

Key details

• Size: M4 x 12 mm (4 mm major diameter, 12 mm length)
• Thread: M4 metric thread (standard for this size)
• Compatibility: designed for use with M4 nuts or tapped holes; ideal for enclosures, brackets, and compact assemblies
• Condition: used; suitable for spare parts, repair projects, and cost-conscious builds

Ideal applications

Perfect for hobbyists, makers, electronics enthusiasts, and technicians who need reliable fasteners without waiting for new stock. Use this M4x12 screw to secure small panels, mount sensors or PCBs to lightweight frames, or complete quick repairs in tight spaces where a shorter fastener is required.

Practical tips for use

• Ensure the receiving hole is clean and free of debris to prevent cross-threading when starting the screw
• Align the component properly before driving to maximize grip and minimize damage to the surrounding material
• Pair with the appropriate driver compatible with the screw head type you receive (drive type may vary by lot)
• Check engagement length: a 12 mm screw should penetrate sufficiently without protruding beyond the opposite side, depending on your material thickness

Whether you’re stocking up for routine repairs or outfitting a new project, this USED M4x12 screw offers dependable performance at thoughtful value. It’s a practical, ready-to-use solution for precise, low-profile fastenings in a wide range of applications.
