Precision Screwdriver Set 32-Piece for Machinery Repair

Product Specifications

Technical details and manufacturing context for Precision Screwdriver Set

Definition

This precision screwdriver set is a component of an Adjustment Tool Set, providing essential tools for fine-tuning, calibrating, and maintaining components in machinery, electronics, and other equipment. It enables technicians to access and manipulate small, recessed, or delicate fasteners that standard tools cannot handle. The set includes 32 pieces, covering a screwdriver tip size range of 0.5–3.0 mm for slotted and Phillips bits, with handle diameters from 18–25 mm and overall lengths from 120–180 mm. The tools are made from hardened tool steel and chrome vanadium steel, with a hardness of HRC 58–62. Torque accuracy is ±5% per ISO 6789, and the set is insulated for live working up to 1000 V AC per IEC 60900. Operating temperature range is -20 to 60 °C, and storage humidity should be ≤85% RH to prevent corrosion. The set weighs 0.8–1.2 kg, making it portable for field service. The working principle involves interchangeable bits mounted on precision-ground, hardened steel shafts; torque applied to the handle is transmitted to the bit tip, which engages with the screw head to apply rotational force. This set is suitable for repair and installation tasks in machinery and equipment. When selecting or verifying a specific model, confirm the actual parameters and standards with the legal manufacturer or supplier, as the values listed are reference ranges for the product category. The set does not include certification or compliance guarantees; standards are provided as procurement references only.

Working Principle

The set utilizes various interchangeable bits (e.g., Phillips, flathead, Torx, hex) mounted on precision-ground, hardened steel shafts. When torque is applied to the handle, it is transmitted through the shaft to the bit tip, which engages with the corresponding screw head to apply rotational force for tightening or loosening. The precision-ground tips ensure a secure fit, reducing cam-out and damage to fasteners. The hardened steel construction provides durability and wear resistance, while the ergonomic handle design allows for precise torque control. The insulation voltage rating of 1000 V AC indicates suitability for live working when properly used and maintained, but always verify the specific model's compliance and condition before use.
