Viga 54-Piece Wooden Nut & Bolt Construction Set - Junior Engineer STEM Toolbox

Engineering Starts Here: 54-Piece Wooden Nut & Bolt Construction Set

Turn, tighten, and transform! Our 54-Piece Wooden Nut & Bolt Set is a comprehensive Montessori STEM resource designed for budding engineers. By using a real wooden screwdriver to assemble planes, robots, and vehicles, toddlers develop precision fine motor skills, logical sequencing, and mechanical problem-solving.

A Professional-Grade Builder's Toolbox:

• Complete 54-Piece Hardware Set: Includes a variety of hole plates (from 2-hole to 6-hole strips), 8 screw cubes, 8 screw discs, 16 colorful bolts, 4 wheels, and a precision-sized wooden screwdriver (137mm).
• Color-Coded Mechanical System: Components in Red, Yellow, Blue, and Green help children categorize and sort parts during construction, fostering early organizational logic.
• Vibrant Realism: From the 50mm wheels to the 38mm screw cubes, every part is sized for high-torque play and realistic structural assembly.

Developmental & Practical Impact:

• Junior Engineering (STEM): Building 3D models from 2D parts introduces concepts of torque, threading, and structural stability.
• Fine Motor Mastery: The twisting motion required for screws is one of the best exercises for wrist strength and finger dexterity, essential for future writing skills.
• Organizational Discipline: Housed in a premium Beechwood storage case (31x31cm) with a transparent acrylic sliding lid, teaching toddlers to clean, sort, and display their tools with pride.

Industrial Quality & Safety Excellence:

• Multi-Wood Craftsmanship: Features a durable Beechwood box, Sophora and Birchwood mechanical parts, and a 1.8mm shatterproof acrylic lid for long-term heavy use.
• Eco-Friendly & Non-Toxic: Finished with premium water-based paints that meet EN71 and GB6675-2014 standards. All threads are smooth and easy for small hands to operate.
• Guidebook Included: Comes with an inspiration manual to kickstart building projects, from simple shapes to complex robots.
