Both faces are identical fields of mushroom-shaped stems.

They interlock with each other rather than one catching in the other.

There is no hook side and loop side to keep track of.

Any piece mates with any other piece.

Only one product needs stocking.

It closes with a distinct audible snap that confirms engagement.

Considerably, particularly in shear.

That suits panel mounting and access covers.

Automotive trim uses it extensively.

It handles fastenings carrying real load rather than just holding position.

Tensile and shear figures are published separately.

Both are typically well above conventional hook and loop of the same area.

Substantially - the stems deform elastically and recover.

Conventional loops break down as hooks pull through them.

Interlocking stems survive far more cycles.

Where a panel is removed frequently over years, that is the reason to specify it.

Manufacturers publish cycle life figures.

The difference is large enough to change the whole-life cost comparison.

Yes - a stem field has far less to catch on than a loop field.

Loops trap lint, hair and fibres and lose engagement as they clog.

Stems shed most contamination instead.

That matters in workshops, vehicles and dusty environments.

It also matters where the fastening is at low level.

Conventional tape in those conditions degrades noticeably faster.

Cost, thickness and the effort needed to separate it.

It is more expensive than conventional tape.

It is generally thicker as well.

The high engagement force means separating takes real effort.

That is an advantage where accidental opening matters.

It is a nuisance where a panel is opened constantly by hand.

Where load, cycle life or contamination defeat conventional tape.

Panel mounting and access covers are typical cases.

Automotive and transport applications use it widely.

Anywhere a fastening must not release accidentally.

Anywhere the fastening is opened many times over years.

For light, frequent, hand-opened fastenings, conventional tape remains easier.

Entirely unchanged where the fastener is adhesive-backed.

Surface preparation remains the main failure point.

Low-energy plastics and textured surfaces still resist bonding.

Bond still builds over hours rather than instantly.

Heat still softens many adhesives.

The stronger fastening actually increases the demand on the adhesive holding it.
