Discover more about the Imperial Ultra Low Head Slotted Shoulder Screws range.
Imperial Ultra Low Head Slotted Shoulder Screws are meticulously designed fasteners optimised for precision assembly tasks, especially within restricted spatial environments. Notably, they possess a minimised slotted head profile coupled with an extended shoulder directly beneath the head, attributes that facilitate a near-flush fitment post-installation. The screws also include a traditional slotted drive, which allows for precise control during the torque application process. They form a vital subset within Accu's comprehensive range of Precision Screws, serving specific industry needs with their unique design characteristics.
How Imperial Ultra Low Head Slotted Shoulder Screws Work
The operational efficiency of Imperial Ultra Low Head Slotted Shoulder Screws is driven by their unique design features. The ultra-low head profile and the extended shoulder enable these fasteners to nestle within pre-drilled imperial recesses in a workpiece, producing a surface that is mostly free of protrusions. The slotted drive offers technicians a high degree of control over torque, minimising the chances of accidental overtightening and subsequent thread damage. These screws are thus an essential resource in applications where precision is paramount, including intricate electronic assembly tasks and high-density mechanical systems.
What Material Are Imperial Ultra Low Head Slotted Shoulder Screws Made From?
Accu's Imperial Ultra Low Head Slotted Shoulder Screws are crafted from A4 Marine Grade Stainless Steel. This high-quality, austenitic stainless steel variant is known for its remarkable resistance to corrosion, especially in challenging environments like marine, chemical, and coastal settings.
Combat vibration-induced loosening with Accu’s pre-applied thread-locking patches. Lock in performance with AccuLock Threadlocker, fortify with Anu-Lok 180, or push the limits with Precote 80.
