Pin screw M3 x 5 mm, Toolcraft (200 pcs) — steel pinol screw

Toolcraft pin screw M3 x 5 mm in steel, pack of 200 pieces, is a small-diameter pinol screw designed for precise fastening and positioning in mechanical and electronic assemblies. The steel construction provides consistent dimensional stability and mechanical strength for repeatable locating and secure connections in prototypes, repairs, and compact mechanisms. The compact size and standardized thread make these M3 x 5 mm pin screws suitable where space is limited and accurate alignment is required.

Advantages

These steel pin screws offer uniform thread and pin geometry for predictable installation torque and secure fit. Supplied in a pack of 200, they reduce part handling and simplify inventory for small-scale production or maintenance. The steel material delivers reliable wear resistance and mechanical rigidity compared with soft materials, making them suitable for repeated assembly and disassembly. Their M3 diameter and 5 mm length are compatible with a wide range of small fastener requirements.

Suitable for

• Mechanical assemblies and fixtures requiring precise locating pins
• Electronics enclosures and PCBs where compact fasteners are needed
• Prototype construction, repairs and small machinery maintenance
• Hobbyist models and precision fitting tasks

Key specifications

• Thread size: M3
• Overall length: 5 mm
• Material: steel
• Pack quantity: 200 pieces
• Type: pin screw / pinol screw for fastening and locating

How to use

Select the appropriate mating threaded hole or nut sized for M3 fasteners. Align components to be located, insert the pin screw through the clearance or threaded hole, and tighten to the required torque using an appropriate screwdriver or hex driver as applicable. For repeatable positioning, ensure mating surfaces are clean and free of debris and verify alignment after tightening. When disassembling, back out the pin screws completely to avoid damage to threads or mating components.

Usage recommendations

Store screws in a dry environment to prevent corrosion and sort by size before use. For applications requiring electrical isolation or additional corrosion protection, consider using insulating washers or surface coatings appropriate to the operating environment.
