OVERVIEW

Premium 18-8 Stainless Steel Fastening Solution

The CPL 3/8-16 X1 1/4 SS18-8 is a high-grade industrial fastener designed to meet the rigorous demands of maintenance, repair, and operations (MRO) across various sectors. Manufactured from 18-8 stainless steel, this component is engineered to provide exceptional resistance to corrosion, oxidation, and chemical degradation. The "18-8" designation refers to the chromium and nickel content (approximately 18% chromium and 8% nickel), which creates a passive oxide layer on the surface that prevents rust formation even in high-humidity or saline environments. This makes it an essential inventory item for facilities management, marine applications, and food processing plants where hygiene and longevity are paramount.

This specific fastener features a 3/8-inch diameter with a standard 16 threads per inch (TPI) Unified National Coarse (UNC) configuration. The coarse thread design is particularly advantageous for general assembly as it is less susceptible to cross-threading and stripping compared to fine threads, while also allowing for faster assembly and disassembly. With a length of 1-1/4 inches, it offers versatile utility for joining materials of moderate thickness or for use in blind holes where depth is a factor. The dimensional accuracy ensures compatibility with standard 3/8-16 nuts and washers, providing a secure and reliable joint.

In the context of machine repair and equipment maintenance, utilizing the correct material grade is critical. While standard carbon steel bolts may offer higher tensile strength in some grades, they lack the inherent environmental protection of stainless steel. For equipment that is exposed to the elements, cleaning agents, or fluctuating temperatures, 18-8 stainless steel is the industry standard for balancing strength with durability. This product is categorized under machine repair parts, reflecting its universal applicability in restoring functionality to welding machines, conveyors, structural frames, and other industrial apparatus.

Whether you are restocking a tool crib or sourcing specific hardware for a critical repair, this stainless steel cap screw delivers the reliability required for professional applications. Its non-magnetic properties (in the annealed condition) also make it suitable for sensitive electronic or magnetic equipment where ferrous interference must be minimized.

FAQ

18-8 refers to the composition of the stainless steel, containing approximately 18% chromium and 8% nickel. This is the most common grade of stainless steel (often equivalent to 304) and offers excellent corrosion resistance.

This bolt has a thread pitch of 16 threads per inch (TPI), which is the standard coarse thread (UNC) for a 3/8-inch diameter fastener.

18-8 stainless steel is generally non-magnetic in its annealed state, but it can become slightly magnetic after cold working or machining. However, it is much less magnetic than carbon steel.

18-8 stainless steel has a tensile strength comparable to Grade 2 or Grade 5 steel bolts (approx. 70,000-100,000 psi). For critical high-stress structural applications requiring Grade 8 strength, a different alloy might be required.

No, 18-8 stainless steel is designed specifically to resist rust and corrosion in outdoor environments, making it an excellent choice for exterior projects.

For a standard 3/8" hex cap screw, you typically need a 9/16" wrench or socket.

Yes, 18-8 stainless steel is widely used in marine environments due to its resistance to saltwater corrosion, although Type 316 stainless is sometimes preferred for submerged applications.
