Specification Library

Welcome to the California Fastener Specification Library, a comprehensive resource for fastener specifications across the various industries we service. These guides offer access to various specifications, standards, and technical resources. It aims to ensure quality and compliance by providing up-to-date information on materials, grades, and regulatory requirements. Our mission is to support the industry and our customers in accessing the critical data necessary for maintaining the highest standards of safety and efficiency in their operations.

Please note this specification guide is intended for general reference only and does not cover every grade and detail of the mentioned ASTM/SAE standards. Users are advised to consult the full ASTM specifications for comprehensive and detailed requirements for their specific applications.

Bolt Specifications

ASTM A193 >

This specification covers alloy and stainless steel bolting materials for high-temperature or high-pressure service and other special-purpose applications, ensuring fasteners are suitable for use in boilers, pressure vessels, valves, and flanges.

ASTM A307 >

ASTM A307 is a specification for carbon steel bolts, studs, and threaded rods of a specified minimum tensile strength, used widely in general applications like anchor bolts, flange bolts, and non-high-strength structural fastening, offering versatility in low-stress and non-critical environments.

ASTM A320 >

ASTM A320 specifies alloy steel and stainless steel bolting materials for low-temperature service, targeting applications in pressure vessels, valves, flanges, and fittings, ensuring toughness and durability in cold environments.

ASTM A449 >

This standard defines quenched and tempered steel bolts and studs with a minimum tensile strength, used primarily in general engineering applications such as construction and machinery where high strength is not as critical as in high-pressure/temperature applications.

ASTM F593 >

ASTM F593 specifies the requirements for stainless steel bolts, hex cap screws, and studs, providing a variety of grades based on chemical composition and mechanical properties to ensure suitability for corrosive environments and general-purpose applications requiring high corrosion resistance.

ASTM F1554 >

Focused on anchor bolts, ASTM F1554 provides specifications for carbon and alloy steel bolts intended for anchoring structural supports to concrete foundations, categorized by strength grades to match varying engineering demands.

ASTM F3125 >

This comprehensive specification covers high-strength structural bolts, combining previous standards like A325 and A490, and includes grades for different strength and atmospheric corrosion resistance needs, pivotal in structural engineering.

Nut Specifications

ASTM A194 >

ASTM A194 encompasses carbon and alloy steel nuts for bolts used in high-pressure and high-temperature environments, offering various grades with different mechanical and chemical properties to suit specific service conditions.

ASTM A563 >

This specification details the chemical and mechanical requirements for carbon and alloy steel nuts used in general structural and mechanical applications, providing a range of grades to match the strength and ductility needed for different fastening scenarios.

ASTM F594 >

ASTM F594 sets the standard for stainless steel nuts, offering a range of grades with specified chemical and mechanical properties, ideal for applications requiring corrosion resistance and strength in general engineering and construction.

Washer Specifications

ASTM F844 >

ASTM F844 covers standard specification for washers, steel, plain (flat), unhardened for general use, providing a range of sizes suitable for use with a variety of bolt diameters, primarily used to distribute the load under bolt heads or nuts to prevent damage to the assembly material.

ASTM F436 >

ASTM F436 is focused on the specification for hardened steel washers used with high-strength bolts in structural and mechanical applications, featuring dimensions and mechanical properties designed to prevent bolt load loss in stressed assemblies.

ASTM F959 >

ASTM F959 details the specifications for compressible-washer-type direct tension indicators (DTIs) for use with structural bolts, designed to indicate when a predetermined tension level has been achieved, thus ensuring the structural integrity and reliability of bolted connections.
