12 point cap screws are engineered for applications that demand secure and tight fastening. Their distinctive head shape maximizes grip, making them ideal for high-torque environments. JingBang stands out as a leading manufacturer and supplier of various grades of stainless steel 12 point cap screws, also known as 12 point flange head cap screws.
Constructed from high-strength materials such as alloy steel and stainless steel, these screws offer excellent tensile strength and wear resistance. Their durability enables them to withstand significant loads and stresses, making them suitable for demanding applications.
jINGBANG 12 point flange head cap screws come with various surface treatments, including zinc plating and black oxide, to improve corrosion resistance and extend service life. This durability ensures their effectiveness in both indoor and outdoor settings, providing reliable performance across diverse conditions.
The head design features twelve points created by overlapping two hexagons, complemented by a flanged underside. Commonly called ferry cap screws, these fasteners are available in sizes ranging from ¼ inches to 4 inches and M6 to M100.
With specifications catering to various applications, metric 12 point cap screws exhibit torque capacities that exceed those of standard socket head screws. Their compact design allows for installation in tight spaces where weight and dimensions are critical, and the absence of recesses prevents debris or fluid accumulation.
These fasteners are offered in multiple types and grades, with 304 and 316 austenitic stainless steel being the most common due to their cost-effectiveness, corrosion resistance, and strength. The 12 point flange head cap screws feature a socket-shaped head compatible with a 12-point driver.
Applications for these screws are widespread in industries such as petroleum, petrochemicals, automotive, and engine components, particularly in environments characterized by high vibration, temperature, and pressure. As a top manufacturer of alloy steel 12 point cap screws, we produce them in large quantities and can easily accommodate orders of any size.

12-point cap screws Specification
Typically, 12-point bolts are commonly found in the oil and gas industry due to their recessed head design, which provides enhanced accessibility for tightening in confined spaces. They are also widely used in engine applications, where clamp loads tend to be higher than in many other contexts. The 12-point configuration is particularly effective in delivering the required torque and maintaining secure connections.
All sizes of 12-point flange bolts are engineered to meet rigorous performance standards, featuring a minimum tensile strength of 170,000 psi and a minimum Rockwell hardness of C37. They also adhere to a Class 3A thread fit for reliable assembly. Notably, ASTM A387 Grade 9 categorizes these bolts as alloy steel, emphasizing their strength and suitability for demanding applications.
12 Point cap Screw Features
The design of a 12-point screw features two overlapping hexagon shapes, resulting in a unique head with twelve points and a flanged underside. These fasteners are also known as ferry cap screws or 12 point flange cap screws. The benefits of this head style include:
– Higher Torque Capability: They offer greater torque capacity compared to standard socket head cap screws.
– Clean Design: The absence of a recess prevents the accumulation of fluid or debris, promoting cleaner applications.
– Compact Size: The smaller head size allows for use in tight spaces, making them ideal for applications where weight savings are crucial.
However, one notable drawback is the increased cost associated with manufacturing these heads.
The Controversy of 6 vs. 12 Point cap screws
The debate over whether 6-point or 12-point bolts are superior continues among professionals. Proponents of 12-point screws argue that the increased number of contact points reduces the likelihood of rounding off during use, while also providing a larger surface area for load distribution.
Despite differing opinions, the ultimate decision should be guided by the specific application rather than a clear-cut determination of which type is better. It’s essential to weigh the advantages of 12-point screws against the additional costs involved in their production to ensure the best choice for your needs.
