Allen Key Screws.

What are Allen Key Screws?

Allen key screws, also known as hex socket screws, renowned for their distinctive hexagonal recess, offer a streamlined yet robust solution for fastening in precision engineering. These Allen head screws accommodate a matching Allen key, enabling high torque application without the risk of cam-out, which plagues conventional screws.

This design not only optimises the interaction between the screw and the tool but also enhances the reliability and longevity of the assembly. Whether it’s securing components in tight spaces or ensuring a sleek finish with countersunk variants, Allen key screws are a testament to engineering ingenuity.

How Allen Key Screws Work

The ingenuity of Allen key screws unfolds upon installation. The Allen screw design allows for tighter fastenings and greater torque control, making them indispensable in industries where precision is paramount. From aerospace to automotive, electronics to DIY projects, the Allen key head can adapt to the most challenging environments.

From securing delicate electronic components with a tiny M1.4 Allen screw or anchoring heavy machinery with a robust M30 Allen screw bolt. Their versatility extends to applications requiring aesthetic appeal, such as furniture design, where the clean lines of Allen head screws contribute to a modern, minimalist look.

What Materials Allen Key Screws Are Made From

Allen key screws are not just about shape; their material composition plays a critical role in their functionality. Ranging from A2 & A4 Stainless Steel for corrosion resistance and high Tensile Steel for strength, to advanced materials like Titanium, RENY, PPS, PEEK, and Polycarbonate for specialised applications, each material brings unique benefits.

For instance, Titanium Allen key head screws offer unparalleled strength-to-weight ratios for aerospace applications, while PEEK screws provide chemical resistance in harsh environments.

What Size and Type Allen Key Screws Are Available

The diversity of Allen key screws on offer from Acuu is evident in their sizes and types. With thread sizes spanning from the minuscule M1.4 to the substantial M30, and lengths from 2mm to 300mm, there’s a screw for every application.

Our lineup includes Allen screw head types such as Head Cap, Countersunk, Button Head, Grub, Flanged, Sealing, Vented variants and more, each tailored for specific needs. To enhance their performance, we offer AccuLock thread locking patches for vibration resistance, AccuBlack chemical blackening for a truly blacked-out aesthetic look and custom manufacture options to meet your unique project requirements.

Incorporating Allen key screws into your projects not only promises a secure and precise fastening solution but also introduces a level of sophistication and reliability that other screws can't match.

FAQs

What are Allen key screws called?

Allen key screws are known by several names including hex socket screws, socket drive screws and screws with Allen key head. These terms stem from the Allen Company, which originated this style of screw, emphasizing their hexagonal recess designed for an Allen key.

What type of screws are Allen bolts?

Allen bolts are a subtype of Allen key screws, characterized by their cylindrical head and hexagonal drive hole. They are designed for high-torque applications, commonly used in machinery, vehicles and where the fastener's head needs to evenly distribute a significant load.

Is hex screw the same as Allen key?

Yes, hex screws and Allen key screws are the same, both featuring a hexagonal recess in the head for an Allen key. Despite different names, their purpose as a secure, high-torque fastening solution remains the same.
