Precision Engineered Shear Screws for the Oil & Gas Industry
Since 1981, Shamrock Precision has been a leader in manufacturing high-quality shear screws for the oil and gas industry in Texas and beyond. Our commitment to excellence and adaptability has made us a global leader in producing precision-machined components with tight tolerances and short lead times.
What are Shear Screws (Mechanical Fuses)?
Shear Screws are specialized fasteners designed with a predetermined breaking point that function as mechanical fuses in oil and gas equipment. These engineered components are manufactured to fail at specific torque or load thresholds, intentionally breaking at designated sections to protect more valuable equipment from damage.
The Critical Role of Shear Screws in Oil & Gas Operations
Shear screws serve as fundamental components in drilling and fracking operations across the oil and gas sector. These specialized engineered fasteners contain a specific weak point that breaks under predetermined force or pressure, serving two main functions:
- Safeguarding other parts or systems, functioning as a mechanical fuse
- Acting as conditional safeguards, preventing mechanism operation until a pressure threshold is reached
In oilfield applications, shear screws allow equipment to engage only when hydraulic pumps reach specific depths and pressures, creating safe and efficient operations. This controlled breakage point helps protect expensive equipment from damage during high-pressure situations.
