Elesa+Ganter BT-HP.20-AV-SST-P-M5X18 Retained Fluted Knob
The Elesa+Ganter BT-HP.20-AV-SST-P-M5X18 retained fluted knob is designed for applications where secure fastening and part retention matter at the same time. This model combines a polyamide-based technopolymer knob body with an AISI 304 stainless steel threaded stud, making it a practical choice for machinery covers, inspection panels, blanking plates, and access points that need to be opened and closed repeatedly.
One of the most useful features of this design is its retained construction. Instead of becoming a loose component during maintenance, the knob remains anchored to the assembly. In real working environments, that helps reduce misplaced hardware, speeds up service operations, and supports a cleaner, safer maintenance routine.
Technical Features
This version uses an M5x18 threaded stud and a 20 mm knob diameter. The overall body proportions are compact, which makes it suitable for installations where there is limited surrounding space. The slotted top design also allows tightening with a screwdriver, which is especially useful when manual grip alone is not ideal or when access conditions are tight.
The black matte technopolymer surface offers a professional finish and a comfortable grip profile. Meanwhile, the stainless steel stud improves resistance to corrosion, which is important in environments exposed to humidity, cleaning agents, or demanding industrial conditions.
Where This Retained Fluted Knob Is Commonly Used
The Elesa+Ganter BT-HP.20-AV-SST-P-M5X18 retained fluted knob is commonly selected for machine guards, enclosures, metal covers, removable access panels, and service doors. Because the knob stays connected to the equipment, it is especially useful in operations where frequent inspection is expected and loose fasteners would create inconvenience or risk.
It is also relevant for industries where cleanliness and material reliability matter, such as packaging machinery, food-related processing equipment, laboratory systems, and general industrial automation.
Why Material Choice Matters
AISI 304 stainless steel is widely preferred where corrosion resistance and dependable mechanical performance are needed. Combined with a PA-based technopolymer knob, the result is a component that balances durability, user comfort, and practical day-to-day handling. For engineers and maintenance teams, that balance is often more important than appearance alone.

Elesa+Ganter BT-HP.20-AV-SST-P-M5X18 FAQ
What type of product is the BT-HP.20-AV-SST-P-M5X18?
It is a retained fluted knob with a stainless steel threaded stud and a screwdriver slot. It is intended for fastening points where the knob should remain attached to the assembly when loosened.
Why is a retained knob useful?
A retained knob helps prevent hardware loss during maintenance or cleaning. This is valuable on machinery covers and access panels that are opened regularly, because the operator does not need to manage a separate loose fastener every time.
Is the stainless steel stud suitable for demanding environments?
Yes. The AISI 304 stainless steel stud offers solid corrosion resistance for many industrial and commercial settings. It is a sensible choice where exposure to moisture or regular washdown conditions can affect standard steel components.
Elesa+Ganter BT-HP.20-AV-SST-P-M5X18 What makes the screwdriver slot important?
The top slot provides an alternative tightening method when extra torque or easier access is needed. This can be particularly helpful in compact installations or service points where hand tightening is less convenient.
What should buyers or engineers check before selecting this model?
The most important checks are thread size, stud length, available mounting space, and the need for retained functionality. In this case, M5 thread compatibility and the 18 mm stud length are key specification points.
