Fractional Size Hex Head Jam Nuts in 18-8 Stainless Steel
Fractional size hex head jam nuts manufactured from 18-8 stainless steel are a premium fastening solution known for strength, corrosion resistance, and long-term reliability. These durable fasteners are widely used in automotive, construction, industrial machinery, and marine-related applications where exposure to moisture, chemicals, or temperature fluctuations is common. Their low-profile design and stainless steel construction make them ideal for securing bolts in demanding environments.
What Are 18-8 Stainless Steel Hex Head Jam Nuts?
Low-Profile Locking Design
A hex head jam nut is thinner than a standard hex nut and is designed to lock another nut or bolt in place. When tightened against a primary fastener, the jam nut creates friction that helps prevent loosening caused by vibration or mechanical stress. The hexagonal shape allows for easy installation using standard hand tools.
18-8 Stainless Steel Composition
18-8 stainless steel, commonly equivalent to Type 304 stainless steel, contains approximately 18% chromium and 8% nickel. This alloy provides excellent resistance to rust, oxidation, and corrosion while maintaining strong mechanical properties. As a result, these jam nuts perform reliably in both indoor and outdoor environments.
