Black Polyurethane Buffer Stop Bolts, M3–M14, 60A / 70A
Selected Select options
Black Polyurethane Buffer Stop Bolts
These AAB threaded buffer stops combine a black polyurethane contact head with a 304 stainless-steel threaded body. They provide a compliant contact point for suitable mechanical stops, cushioning or protective-contact arrangements in industrial machinery. They are individual machine components; selecting a bolt does not define a complete shock absorber or a rated safety stop.
Construction and Material
Item
Source specification
Threaded body
304 stainless steel; metric coarse thread
PU contact head
Black, solid contact face
Hardness
70 Shore A for offered M3–M12 sizes; M14 original cards explicitly state 60 Shore A
Thread range
M3, M4, M5, M6, M8, M10, M12 and M14 among reviewed selections
Drive/construction reference
Supplier inset shows the bolt head before PU molding. Do not assume an exposed hex-socket drive through the solid contact face.
Supply
One selected buffer stop bolt. Nuts, washers, brackets, machines and grouped samples are not specified as included.
Choosing the Correct Model
The model format is AAB-M(thread)×thread length-head diameter×head height. All model dimensions are millimetres. Match all four values and the thread pitch; equal threads with different PU heads are separate options. Some original cards also show a numeric AAB image reference before the model. The selected option, original arrows and dimension schedule identify the actual geometry. Inches use25.4 mm per inch and are rounded to three decimals; the thread itself remains metric.

Applications
Suitable designs can use a PU head for end-position contact, workpiece protection or cushioning within machinery and fixtures. Supplier application references include automotive production, pharmaceutical machinery, electronics machinery and paper equipment. Those photographs illustrate industrial contexts; they do not establish certification, hygiene suitability or a tested installation for this specific component.
Selection and Installation
Measure the required metric thread, exposed thread length, PU head diameter, head height and available mounting space.
Check the exact thread pitch, mating-hole depth, thread engagement, retention and backing structure.
Confirm contact energy, force, compression, operating cycle, temperature and chemical exposure with the actual machine requirements. No complete-bolt load, energy, speed or compression limit is supplied.
Use a mounting and tightening method compatible with the supplied bolt construction. Avoid twisting, cutting or clamping the PU head in a way that damages the coating or bond.
Secure the installation and test contact and clearance under controlled conditions. Inspect for looseness, wear or coating damage during service.
Hardness and Source Selection Notes
M14 cards state black 60A and are explicitly labelled 60A here. Other reviewed offered sizes show black 70A. Generic family imagery showing red 50A or natural 90A is a comparison, not the offered coating. A source option whose 60 mm thread label conflicts with a 70 mm arrow is excluded. M16 rows without exact original images and the unspecified other-size placeholder are not offered.
Custom Requests and Supply
For an unlisted design, send a drawing with thread, pitch, thread length, head diameter, head height, hardness, quantity and machine duty to boltte@boltte.com. A custom request requires confirmation of its geometry and price. No blanket performance rating, certification, delivery promise or accessory bundle is inferred from the supplier material.
Original Product, Drawing and Application Images
The following translated originals retain the supplied product photographs and dimension lines. They include family views, material/construction close-ups, a source construction drawing, application contexts and sample model cards. Every offered standard model has its own upper-gallery dimension image with mm and inch references.
