Hand Screwdriver Manufacturer – Precision Assembly Tools for Industrial Use
Ningbo Tongque Machinery Manufacturing Co., Ltd. (FLONPRO) supplies a complete range of Hand screwdriver products designed for assembly lines, maintenance workshops, and field service. As a professional hand screwdriver manufacturer with 15 years of experience in power and hand tools, we produce screwdrivers that meet the torque, durability, and ergonomic requirements of demanding B2B applications. Our factory in Ningbo operates a 10,000 sq.m. facility with end-to-end quality control, from raw material inspection to final function testing.
We offer OEM and ODM services for distributors, tool brands, and industrial procurement teams. Each screwdriver is built with CR-V steel (chrome-vanadium) shafts, precision heat-treated tips, and ergonomic handles for repetitive use. The range covers flathead, Phillips, and other common drive types in multiple lengths and tip sizes.
Our Hand Screwdriver Range

All models are available in flathead and Phillips tip configurations. Custom tip profiles, shaft lengths, and handle colors can be specified for OEM orders.
Application Fit and Workpiece Considerations
Our hand screwdrivers are intended for manual fastening of screws in:
- Electrical and electronic assembly – control panels, terminal blocks, consumer electronics.
- Furniture and cabinetry – cam locks, hinge screws, drawer slides.
- Automotive and machinery maintenance – interior trim, clamps, covers.
- HVAC and plumbing – ductwork, valve covers, fixture mounting.
The CR-V steel shaft provides high torsional strength and wear resistance. Magnetized tips (LM1112, LM1718) hold screws securely during positioning, reducing dropped fasteners and rework. For applications requiring extra hardness, the LM1314 model undergoes additional heat treatment to resist tip deformation in high-torque scenarios.
Critical Specifications and Performance
Each screwdriver is manufactured to the following baseline standards:
- Shaft hardness: 48–52 HRC (Rockwell C) after heat treatment.
- Tip geometry: Precision ground to ISO 2380 (flathead) or ISO 8763 (Phillips) tolerance.
- Handle grip: PP+TPR overmold for oil resistance and reduced hand fatigue.
- Magnetic retention: Remanent magnetization ≥ 500 Gauss at tip (magnetized models).
We do not claim specific torque ratings for hand screwdrivers, as applied torque depends on operator technique. Instead, we focus on shaft integrity and tip fit to minimize cam-out and fastener damage.
Quality Assurance and Testing
Our factory implements stage-gate quality control:
- Incoming material: Chemical composition analysis of CR-V steel rod.
- In-process: Dimensional checks after forging, heat treatment, and grinding.
- Final inspection: Visual, hardness test, magnetic flux measurement, and fit test with standard screw gauges.
Samples from each production lot are retained for traceability. We can provide inspection reports upon request for bulk orders.
Customization and OEM/ODM Services
We support custom branding, packaging, and specification modifications. Typical customization options include:
- Laser-engraved logo on shaft or handle.
- Custom handle color (Pantone match).
- Non-magnetized tip option.
- Alternative shaft length or tip size not in standard range.
- Blister card, clamshell, or bulk polybag packaging.
Minimum order quantities apply for custom production. Contact our sales team with your target quantity and delivery timeline.
Packaging and Delivery
Standard packaging: individual polybag with hang tag, or bulk pack of 10 pieces. Export cartons are designed for container loading. Our location near Ningbo Port and Shanghai Port enables efficient FOB, CIF, CFR, and EXW shipping. We coordinate with your forwarder or arrange logistics through our partner carriers.

Frequently Asked Questions
Q: Are FLONPRO hand screwdrivers suitable for precision electronics work?
A: Yes, models LM1112 and LM1718 feature magnetized tips that hold small screws securely, reducing the risk of dropping fasteners onto circuit boards. The CR-V steel shaft provides the necessary hardness for clean engagement without stripping screw heads.
Q: Can I order a custom screwdriver with a non-standard tip size?
A: We can produce custom tip sizes and shaft lengths under OEM agreements. Please provide the required tip dimensions and expected quantity for a feasibility review.
Q: What is the minimum order quantity for OEM hand screwdrivers?
A: MOQ depends on the complexity of customization. For standard models with logo engraving, MOQ starts at 500 pieces per SKU. For fully custom handles or packaging, MOQ is typically 1,000 pieces.
Q: Do you provide samples before mass production?
A: Yes, we can supply pre-production samples for approval. Sample lead time is 7–10 days after design confirmation. Sample cost is deducted from the final invoice for bulk orders.
Q: How do you ensure the screwdriver tip does not break under high torque?
A: Our CR-V steel shafts undergo controlled heat treatment to achieve 48–52 HRC hardness, balancing toughness and wear resistance. Each production lot is tested for hardness and tip geometry before release.
