Socket Drive Screws.

What are Socket Drive Screws?

Socket drive screws, commonly known as socket screws or socket head screws, are high-precision fasteners with a unique internal wrenching feature. This design allows them to be used in a multitude of applications, including those with limited clearance, where traditional external wrenching is not feasible. The head of a socket screw features a hexagonal six-sided recess designed for an Allen or hex key. There are various types of socket head screws available such as socket head cap screws, countersunk, button, pan head, shoulder and grub, these screws offer individual versatility for different applications.

How Socket Drive Screws Work

Socket drive screws are integral in precision engineering, renowned for their strength and reliability. They are used in a myriad of scenarios, from electronic devices to large-scale manufacturing equipment. For instance, the small-sized M1.4 socket screws are ideal for intricate electronic assemblies, whereas larger M30 screws are suited for heavy-duty machinery.

Their internal hexagon socket drive system provides a more secure and less obtrusive method of fastening, making them a preferred choice for sleek, high-end designs or applications requiring quick assembly.

Material Makeup of Socket Drive Screws

The material composition of Accu's range of hex socket screws is diverse, ranging from A2 & A4 stainless steel to high tensile steel, titanium, RENY, PPS, PEEK, and polycarbonate. Each material offers unique attributes.

Stainless steel variants are known for corrosion resistance, making them ideal for outdoor or marine environments. Titanium screws offer unparalleled strength-to-weight ratios, essential in aerospace applications. Synthetic materials like PEEK and polycarbonate provide excellent thermal and chemical resistance, suitable for specialized industrial applications.

Size, Type, and Finishes of Socket Drive Screws

Socket drive screws at Accu come in sizes from the diminutive M1.4 (1.4mm) thread to the robust M30 (30mm) thread, with lengths spanning from 2mm to 300mm. The diverse range of head types ensures suitability for various design requirements.

Additional finishes like AccuBlack chemical blackening enhance corrosion resistance and offer a reflection-free matte black aesthetic appeal, perfect if you're looking for black socket screws. Alternatively, AccuLock thread locking patches increase the screw’s resistance under vibrations, preventing loosening. Special custom manufacturing options are also available to meet unique project specifications. Open up a discussion with one of our engineers to learn more.

FAQs

Q: What is a socket screw called?

A: A socket screw, also known as a socket head screw, is characterised by its internal wrenching system and is typically driven with an Allen or hex key. There are many types of socket screws each identifiable by its unique head profile.

Q: Why use a socket head screw?

A: Socket head screws are used for their high tensile strength, precise application, and the ability to be fastened in tight spaces where traditional screwdrivers cannot reach.

Q: What is the difference between a socket screw and a hex bolt?

A: The primary difference lies in the drive system: socket screws have an internal hex drive, while hex bolts have an external hex head suitable for wrenches or spanners.

Q: Do socket head screws need washers?

A: While not always necessary, washers can be used with socket head screws to distribute load, prevent damage to surfaces, and provide a more secure fastening in certain applications.

Q: Are socket drive screws suitable for high-torque applications?

A: Yes, hex socket screws are designed for high-torque applications due to their robust construction and internal drive system, which allows for a more secure grip and higher torque application compared to standard screws.
