Hammer Drive Anchors

South Coast Fasteners, Inc. supplies drive screws built for permanent fastening where security and durability are top priorities. Drive screws, sometimes referred to as hammer drive screws, are designed to be driven into pre-drilled holes where their specially designed threads create a tight interference fit. This tamper-resistant fastening method makes them ideal for attaching nameplates, signage, and other components that should not be easily removed.

South Coast Fasteners offers drive screws in both zinc-plated steel and stainless steel grades, ensuring reliable performance across industrial, marine, and construction environments.

Material Options

South Coast Fasteners stocks drive screws in durable materials engineered for secure, permanent fastening.

Carbon Steel

Carbon steel provides strength and reliability for drive screws used in standard applications. It is cost-effective and well-suited for indoor use, signage, and machinery plates. When paired with protective finishes such as zinc, carbon steel provides moderate corrosion resistance and consistent performance.

Stainless Steel 304

Stainless steel 304 is the premium option for drive screws that must withstand outdoor, marine, or chemical exposure. It provides strong resistance to rust and corrosion, making it ideal for equipment labeling, food-grade environments, and coastal installations. This material ensures fasteners remain secure and dependable even in challenging conditions.
