Hand Tools Inspection Processes

Every manufacturer knows the importance of providing quality products to their customers. In order to always get a quality product, it is very important to perform different tests and inspection processes to ensure the reliability, safety and ease of use of the product.

The following are a few standard quality inspection procedures that are common to most hand tools:


Hand Tools1. Pre-Production Inspection

The purpose of this inspection process is to verify that all equipment or machinery required for hand tool production is free from any damage, defects or any deterioration to ensure competent and consistent production at the start of the operation. Any equipment that shows any defects should be repaired or replaced as soon as possible to avoid the risk of producing defective products.

2. Raw Materials Inspection

The purpose of this inspection process is to thoroughly check and verify that all required materials used for molding, hardening, cooling and assembly are complete and in good condition to ensure that all materials to be used are free of any damage or defects prior to starting the production process.

3. Assembly Inspection

The purpose of this inspection process is to verify that all specifications of all assemblable parts in the product meet the job or quality requirements so that it can be considered in the next production queue.

4. Coating Inspection

The purpose of this inspection process is to verify that all hand tool surfaces that require metal coating are evenly and completely coated. The coating is closely related to the performance and longevity of the metal, and therefore affects the quality of the hand tool. Each hand tool that has been missed during the coating process will be recoated to save production time.

5. Visual Inspection

The purpose of this inspection process is to thoroughly inspect all hand tools for any visible damage, dents, cracks, nicks or any known production anomalies to ensure that all hand tools in the queue are ready for the next set of inspection processes.

6. Weight And Measurement Inspection

The purpose of this inspection process is to accurately measure different hand tools under the same category to ensure that all tools are uniform and meet design requirements in terms of height, weight, size and diameter.

7. Hands On/Quality Control Inspection

This inspection process is actually an in-use test to check how each hand tool product performs in use to determine if they meet the quality standards required for the job. For example, whether the hand tools can provide sufficient force or speed, withstand the wear and tear of the job, etc., are the focus of hands on inspection.


Above, are the quality control tests that will be applied in the production of hand tools nowadays. Manufacturers should be familiar with and strictly follow these processes to ensure the production of quality hand tools. Retailers should also be aware of them so that they can better manage their supply chains.
