stainless steel self tapping hex head screws

EPDM, a synthetic rubber, is known for its excellent resistance to heat, ozone, and numerous chemicals, making it an ideal material for manufacturing washers used in fastening systems. The addition of a washer to a fastener significantly enhances its functionality by distributing the load evenly, preventing damage to the mating surfaces, and ensuring a tight seal. The EPDM washer, with its resilient nature, adds an extra layer of protection against leaks and environmental ingress.

Bolts are among the most commonly used structural fasteners. They consist of a threaded shaft with a head at one end and are typically used in conjunction with nuts to create a strong joint between two or more components. Bolts can be found in various grades and materials, allowing for a range of tensile strengths and corrosion resistance. Common types of bolts include hex bolts, carriage bolts, and anchor bolts. Hex bolts are often used in heavy construction applications, while carriage bolts are ideal for applications where a smooth, rounded head is desired.

Firstly, the material choice plays a significant role. Steel, being the most common material, is available in different grades like carbon steel, stainless steel, and alloy steel. The grade determines the rod's durability, resistance to corrosion, and overall performance, which can significantly impact the price. For instance, a higher-grade stainless steel rod will generally cost more than a standard carbon steel one due to its superior properties.
