Product Description
Customer Questions & Answers
-
Question:
What materials are used for Class 10.9 steel cap screws?
Answer: Class 10.9 steel cap screws are primarily made from high-strength carbon steel, which is then heat-treated to enhance its mechanical properties. This composition ensures that the screw possesses excellent tensile strength and durability, making it suitable for demanding applications such as construction, automotive, and machinery assembly. Its robustness allows it to withstand significant loads and stresses, making it a reliable choice for both professional and DIY projects. -
Question:
How does the plain finish on these cap screws affect their performance?
Answer: The plain finish on Class 10.9 steel cap screws provides a clean, unfettered surface that enhances grip and allows for proper torque application during installation. While it may lack corrosion resistance, this finish is ideal for environments where painting or coating is subsequently applied. For example, when used in permanent installations or machinery, applying a protective coating can further enhance longevity while maintaining the benefits of the plain finish during assembly. -
Question:
Are these screws suitable for outdoor use?
Answer: While Class 10.9 steel cap screws offer high strength, their plain finish makes them less resistant to environmental factors such as rust and corrosion when used outdoors. For outdoor applications, it is advisable to apply a protective coating or use screws specifically designed for corrosion resistance, such as those made of stainless steel. This ensures that the screws maintain their structural integrity and performance under varying environmental conditions. -
Question:
What tools are required for driving Class 10.9 hex head cap screws?
Answer: To install Class 10.9 hex head cap screws, you typically need a standard socket wrench or a spanner that fits the specific size of the hex head. For optimal tightening, a torque wrench helps in applying the correct amount of torque, preventing over-tightening which can lead to stripping the threads. This makes them ideal for both mechanical assemblies and construction projects where precise torque specifications are crucial. -
Question:
What does 'fully threaded' mean in reference to these cap screws?
Answer: A 'fully threaded' cap screw means that the entire length of the shank is covered with threads, allowing it to be engaged at any point along its length. This design provides flexibility in how deep the screw can penetrate into the material, providing versatile applications in various fastening scenarios. For instance, when fastening to materials of varying thicknesses, fully threaded screws offer greater gripping power and adaptability. -
Question:
What does M6-1 metric coarse threads indicate?
Answer: The M6-1 designation indicates that the screw has a diameter of 6 mm and a coarse thread pitch of 1 mm. Metric coarse threads are designed for efficient assembly and are commonly used in standard mechanical applications, offering a balance of strength and ease of installation. This threading also helps avoid cross-threading, making it user-friendly for most environments, including automotive and machine assembly. -
Question:
Can Class 10.9 cap screws be used in high-stress applications?
Answer: Yes, Class 10.9 cap screws are designed for high-stress applications due to their high tensile strength, making them suitable for heavy-duty environments such as steel construction and automotive manufacturing. Their durability allows them to maintain performance under significant load conditions, ensuring structural integrity where strong fastening is essential, such as in supporting frameworks or high-load machinery. -
Question:
What are DIN 933 and ISO 898 standards in relation to these screws?
Answer: DIN 933 and ISO 898 are international standards that dictate the specifications for hexagon head screws, including materials, dimensions, and mechanical properties. These standards ensure that Class 10.9 cap screws are manufactured consistently and meet rigorous safety and quality criteria, making them reliable for critical applications. Compliance with these standards assures users of the screws' performance in various assembly and fastening situations. -
Question:
How can I identify a Class 10.9 screw if not marked?
Answer: In the absence of markings, identifying a Class 10.9 screw involves looking for specific characteristics, such as its thread pitch and material strength. Often, you will find that they have a high-grade finish and a distinct heft due to their carbon steel composition. However, for assured identification, consulting specifications or manufacturer details is advised. Utilizing a thread gauge can help measure and confirm the thread pitch and diameter. -
Question:
Where can I buy Class 10.9 Steel Cap Screw, Plain Finish, Hex Head, External Hex Drive, Meets DIN 933ISO 898, 16mm Length, Fully Threaded, M6-1 Metric Coarse Threads?

SmallParts Hex Bolts Editorial Review
The Class 10.9 Steel Cap Screw seems to be performing well for customers who have used it to bolt components onto their engines. One customer specifically mentioned using it on a 5.9 24v Cummins engine with success. The quality of the product has been praised, with users noting that it is as advertised. Some customers also appreciated the competitive pricing of the screw. However, one user pointed out a discrepancy in the expected wrench or socket size needed for the bolt, highlighting the need for a 3/4" socket instead of the anticipated 18mm one. Overall, the Class 10.9 Steel Cap Screw appears to be a reliable and well-priced option for users looking for a durable bolt for mechanical applications. **
