Parker Fastener NAS1351/NAS1352 Socket Head Cap Screws:
Superior Materials, Finishes, and bisco industries’ Competitive Pricing.
Parker Fasteners, a leader in precision fastener manufacturing, specializes in producing high-quality socket head cap screws that adhere to National Aerospace Standards (NAS), specifically the NAS1351 and NAS1352 series. These screws are essential to aerospace and industrial applications, offering exceptional performance and reliability.
Materials and Their Advantages:
Parker Fasteners manufactures NAS1351 and NAS1352 screws using premium materials, each selected for specific performance attributes:
- Alloy Steel: Known for its high tensile strength and durability, alloy steel ensures that the screws can withstand significant mechanical stress, making them ideal for critical structural applications.
- Corrosion-Resistant Steel: This material offers excellent resistance to oxidation and corrosion, extending the lifespan of the screws in harsh environments
- Heat-Resistant Steel : providing reliable performance in high-temperature conditions. Stainless steels are highly resistant to oxidation, particularly at elevated temperatures. These steels are non-magnetic and maintain their toughness at both high and low temperatures.
Finishes and Their Benefits:
To enhance the performance and longevity of NAS1351 and NAS1352 screws, Parker Fasteners offers various finishes:
- Passivation: This process removes surface contaminants from stainless steel, enhancing its natural corrosion resistance and ensuring optimal performance in corrosive environments.
- Cadmium Plating: Provides excellent corrosion resistance and lubricity, which is crucial in aerospace applications where components are exposed to harsh environments.
- Black Oxide: Offers mild corrosion resistance and an attractive black finish, suitable for applications where aesthetics and minimal light reflection are important.
Key Differences Between NAS1351 and NAS1352 Screws:
While both NAS1351 and NAS1352 screws are socket head cap screws used in aerospace applications, the primary distinction between them lies in their thread pitch:
- NAS1351: Specifies socket head cap screws with a fine thread pitch.
- NAS1352: Specifies socket head cap screws with a coarse thread pitch.
Advantages of Each Thread Type:
Fine Threads (NAS1351):
- Higher Tensile Strength: Fine threads have a larger minor diameter, which can result in higher tensile strength.
- Better for Hard Materials: They are more suitable for hard materials, providing a tighter fit.
- Enhanced Vibration Resistance: Fine threads are less likely to loosen under vibration due to their shallower thread angle.
Coarse Threads (NAS1352):
- Faster Assembly: Coarse threads engage more quickly, facilitating faster assembly processes.
- Better for Soft Materials: They are more suitable for softer materials, providing better grip and reducing the risk of stripping.
- Improved Resistance to Thread Damage: Coarse threads are less susceptible to damage and are easier to repair if damaged.

What is a Locknut?
A locknut is a nut specifically designed to stay fastened despite vibration or other environmental stresses. In order to stay locked in placed locknuts utilize surfaces that increase friction and reduce the possibility of the nut coming loose. The most common way to increase the surface friction is to add a nylon patch to the locknut’s threads. In some cases friction is also increased by fabricating locknuts with a slightly oval shape. Locknuts come in in various types including jam nuts, speed nuts, flex-top locknuts, distorted-thread locknuts, and castle nuts.
Locknut Applications
Needless to say, high quality and reliable locknuts are integral to many applications. Some of the most popular applications for locknuts are aircraft, military equipment, and machinery. These applications typically experience high stress and it is critical for safety and performance that components stay securely fastened.
Locknut Suppliers
Popular locknut brands include SPS Flexloc, MacLean ESNA, Micro Plastics, and Republic (Alcoa). Thanks to companies like Nylok standard nuts can also be converted into locknuts by adding a nylon patch. For more detailed locknut specifications and technical info view MacLean ESNA’s Catalog.
