Cheese head screw with low head | TX | A4 | ISO 14580
Are you looking for a reliable fastening solution for demanding environments? ISO 14580 cheese head screw (Torx) in stainless A4 is designed to provide secure fastening and a long service life, even in corrosive and exposed environments. The low cheese head, combined with the Torx recess, provides effective power transmission and reduces the risk of cam-out during installation. The design enables stable assembly where low installation height is required without compromising strength or function.
FIELD OF APPLICATION
Ideal for fastening where a low head is required and where the space above the joint is limited, for example in machine building, construction, automotive, marine installations, and industrial structures. The Torx recess provides high torque transmission and secure assembly with reduced tool wear. The screw is particularly well-suited for environments where corrosion resistance and operational reliability are critical.

FREQUENTLY ASKED QUESTIONS (FAQ)
What characterizes a cheese head screw according to ISO 14580 with Torx?
ISO 14580 is a cheese head screw with a low screw head and internal Torx recess (TX). The design of the low head makes it ideal for tight spaces and countersunk holes where installation height is limited. The Torx grip ensures optimal power transmission and prevents the tool from slipping or damaging the recess during installation.
Why is acid-proof A4 / AISI 316 the best choice for this screw?
A4 steel (AISI 316 / 1.4401) contains molybdenum, which provides maximum corrosion protection against saltwater, aggressive chemicals, and road salt. This makes the screw indispensable in marine environments, the chemical industry, food processing, and coastal areas where regular A2 screws risk corroding over time.
Why is Torx (TX) preferred over hex (Allen) for screws with a low head?
Because low screw heads have a shallower tool recess, there is a risk that a classic hex recess (Allen) will round out at higher tightening torques. The Torx pattern distributes torque evenly over six vertical contact surfaces, which provides a more secure grip, reduced tool wear, and enables efficient mechanical installation.
