Cylindrical Low Head

Low Head Cap Screws: In situations where clearance is tight, our low-head cap screws offer a compact yet resilient fastening solution. Despite their reduced profile, these screws deliver the same level of performance you've come to expect from Newport Fasteners. A low-head socket head cap screw, also known simply as a low-head cap screw, is a type of fastener similar to a standard socket head cap screw but with a reduced head height. Like its standard counterpart, a low-head socket head cap screw features a cylindrical shaft with a recessed hexagonal socket drive (often referred to as an Allen drive) at one end.

The distinguishing feature of a low-head cap screw is its head, which is shorter in height compared to a standard socket head cap screw. This reduced head height allows the screw to sit flush or near-flush with the surface of the material being fastened. As a result, low-head cap screws are commonly used in applications where clearance is limited or where a lower profile is desired for aesthetic reasons.

Despite their smaller head size, low-head socket head cap screws offer the same level of strength and durability as standard socket head cap screws. They provide reliable clamping force and can withstand high levels of torque, making them suitable for a wide range of fastening applications in various industries, including automotive, aerospace, machinery, and electronics.

Overall, low-head socket head cap screws are valued for their versatility, strength, and ability to provide a secure fastening solution in tight spaces or where a sleek, low-profile finish is desired.

Low head socket head cap screws are typically manufactured to meet industry standards and specifications for dimensional accuracy, mechanical properties, and material composition. The specific standards may vary depending on the intended application and the requirements of the customer or industry.

Some of the common standards and specifications that low head socket head cap screws may adhere to include:

ASME B18.3: This is the American Society of Mechanical Engineers (ASME) standard that specifies dimensions, tolerances, and performance requirements for socket head cap screws, including low head variants.

ISO 4762: This is the International Organization for Standardization (ISO) standard for hexagon socket head cap screws. It provides dimensional specifications for various sizes and types of socket head cap screws, including low head variants.

ASTM F835: This specification covers the requirements for alloy steel socket button and flat countersunk head cap screws. While not specific to low head cap screws, it provides requirements for material composition and mechanical properties that may apply to certain variants.

DIN 6912: This is the German Institute for Standardization (DIN) standard for low head socket cap screws. It specifies dimensions, tolerances, and technical requirements for these fasteners.

Manufacturers may also adhere to customer-specific requirements or industry standards applicable to their particular application or market.

In addition to meeting dimensional and mechanical specifications, low head socket head cap screws may also be manufactured from various materials, including alloy steel, stainless steel, and other specialty alloys, depending on the requirements of the application and environmental conditions. These materials are often specified based on factors such as corrosion resistance, strength, and temperature resistance.
