Screw Cimco 193113 50 mm Zinc plated steel Round head 4.5 mm diameter

The Cimco 193113 screw is a 50 mm zinc‑plated steel fastener with a round head and a 4.5 mm thread diameter. Designed for general fastening tasks, this single-piece screw provides corrosion resistance from its zinc coating and mechanical strength from its steel core. Its round head offers a smooth, low-profile finish suitable where a domed head is preferred over countersunk styles.

Advantages

The zinc plating improves resistance to rust and extends the service life of the steel screw in typical indoor and sheltered outdoor environments. The 4.5 mm thread diameter balances load-bearing capability and ease of installation into pre-drilled holes or matching nuts. The round head design reduces the risk of snagging and provides a uniform appearance on visible surfaces. Being a single-piece supply makes it suitable for small repairs or one-off installations.

Suitable for (tasks / use cases)

• Furniture assembly and small carpentry repairs
• Mounting brackets, panels, and light fixtures in indoor settings
• Repairing household appliances and accessories where a rounded head is required
• Fastening into metal or wood with pre-drilled pilot holes

Key specifications

• Length: 50 mm
• Material: zinc plated steel
• Head type: round head
• Thread diameter: 4.5 mm
• Quantity: 1 piece

How to use

Select an appropriate driver that matches the screw head profile and ensure a proper pilot hole has been drilled into the workpiece to prevent splitting or thread damage. For metal-to-metal applications, use a matching nut or a threaded insert as required. Apply steady, controlled torque when driving the screw to avoid stripping the head or over‑tightening; stop when the round head seats against the surface. If corrosion protection is a concern in exposed outdoor locations, consider additional sealing or using a stainless alternative.

Usage recommendations

Verify material compatibility before installation, use correct pilot hole diameter for the 4.5 mm thread, and use hand or power tools at moderate speed to ensure clean engagement of threads and to preserve the zinc plating.
