- Инспекција материјала: Chemical composition analysis, Mechanical performance testing (tensile strength, yield strength, elongation), Hardness testing, Surface hardness, Decarburization layer inspection
- Surface Treatment Inspection: Coating thickness, Coating quality (free of bubbles, cracks, peeling), Surface color and gloss, Corrosion test
- Тхреад Инспецтион: Integrity and continuity of threads, Shape and precision of threads (thread angle, half-thread angle), Cleanliness of threads (free of contaminants, iron filings)
- Инспекција изгледа: Surface defects such as scratches, pits, cracks, etc., Compliance of appearance with design requirements
- Функционално испитивање: Bolt torque testing, Tensile testing (simulating actual usage conditions)
- Инспекција паковања и етикетирања: Packaging firmness, cleanliness, dryness, Clarity and correctness of labeling

Spot Check Results

In this spot check, 2 batches of non-conforming products were found, with a non-conforming discovery rate of 0.149%. For the non-conforming products, the company has taken the following measures:

Цонсумер Типс

To protect the rights and interests of consumers, here are some common sense tips for purchasing and using fasteners:
Precautions When Purchasing:
1. Check the product label or tag to ensure accurate information.
2. Carefully inspect the product appearance to avoid defects such as scratches, pits, and cracks.
3. Select products based on their functional classification and grade.
4. Analyze the relationship between price range and product quality, and avoid using price as the sole basis for purchase.
 Мере опреза приликом употребе:
1. Consumers should preferably use bolts and nuts with similar performance grades to maximize the performance of standard fasteners. Generally, grade 4 nuts are paired with grade 4.8 bolts, grade 5 nuts with grade 5.8 bolts, and so on. A nut with a lower performance grade can be replaced by one with a higher grade, but not vice versa.
2. Consumers should purchase fasteners of the appropriate grade based on actual needs. If an 8.8 grade bolt meets the requirements, there is no need to purchase a 10.9 grade bolt, and one should not purchase bolts below 8.8 grade just because of lower prices, as this could lead to immeasurable losses.
