Carbon Steel Coated Self-tapping Screw
High Hardness · Corrosion Resistance · Long Service Life
OVERVIEW
Overview of Carbon Steel Coated Screws
01. Introduction to Infasron Carbon Steel Coated Self-Drilling Screws
Infasron carbon steel coated self-drilling screws are highly efficient multi-functional fasteners that integrate drilling, tapping, and fastening into one.
The carbon steel coated self-drilling screws are made of high-strength carbon steel material to ensure excellent drilling capability and tensile strength;
The surface of the carbon steel coated self-drilling screws has undergone special coating treatment (STALGARD coating, withstanding up to 2000 hours of salt spray testing and 25 acid rain cycles; supports customized color coatings), providing superior rust and corrosion resistance to easily handle various indoor and outdoor environments;
The carbon steel coated self-drilling screws require no pre-drilling and can be rapidly installed directly onto base materials such as steel structures and metal sheets, greatly enhancing construction efficiency and connection reliability.
02. Steel Structure Fastening Challenges, Infasron Solves Them for You
Cumbersome traditional fastening methods
Large deviations in pre-drilling
Ordinary fasteners are prone to corrosion
Vibration leads to loosening
Tight project schedules
ADVANTAGES
Core Advantages of Carbon Steel Coated Screws
Hardness Enhancement via Carburizing Heat Treatment
Through the carburizing heat treatment process, the surface hardness of the screw is significantly increased to HRC53 or above, while the core hardness is maintained within the range of HRC32-40. Screws treated with carburization possess both high hardness and strong toughness, which remarkably improves the work efficiency of workers on-site.
Excellent Mechanical Performance
Infasron carbon steel coated self-drilling screws can provide a torque as high as 10N, a value that significantly exceeds the 8N torque typically provided by other manufacturers in the market. The average load-bearing capacity of Infasron carbon steel coated self-drilling screws is approximately 15% to 20% higher than ordinary self-drilling screws available on the market.
No Hydrogen Embrittlement Phenomenon
The entire process utilizes room-temperature environmental treatment, avoiding high-temperature tempering steps and thereby ensuring that the strength of the screw is maintained. The production process involves no acid washing and does not rely on external electric fields, effectively preventing the phenomenon of hydrogen embrittlement in the screws and ensuring product safety and reliability.
Superior Corrosion and Wear Resistance
The surface treatment utilizes STALGARD coating technology, which can effectively resist the erosion of fasteners by various corrosive environments, enhancing corrosion resistance and durability. The anti-corrosion grade (C1-C4+) can be customized according to project requirements, passing up to 2500 hours of salt spray testing and 30 acid rain cycles.
Environmental Protection and Compliance Guarantee
The production process strictly follows EU RoHS environmental standards. The products do not contain any restricted hazardous substances, including but not limited to Lead (Pb), Cadmium (Cd), Mercury (Hg), and Hexavalent Chromium (Cr6+). This compliance with global environmental regulations helps customers expand into broader market spaces.
