Type I cross recessed flat countersunk trim head tapping screws with Type AB thread forming are a widely specified fastener combining a shallow, smaller‑diameter countersunk head with the industry’s most commonly used thread‑forming point design. The trim head profile sits nearly flush with the workpiece surface but uses a smaller head diameter and lower head height than a standard flat…

Cross recessed countersunk head tapping screws are designed to form their own mating thread when driven into a pre‑drilled or punched pilot hole, eliminating the need for a separate tapping operation. The countersunk head sits flush with the workpiece surface, providing a smooth finish suitable for applications where a snag‑free profile is required. The cross recess (Phillips or Pozidriv, depending…

Slotted countersunk head machine screws feature a flat, tapered head designed to sit flush with the workpiece surface when installed into a pre-drilled countersunk hole. The straight slot drive provides a simple and widely compatible method of installation with a standard flat-blade screwdriver. Dimensions and technical requirements are defined by DIN EN ISO 2009, which has superseded the older DIN…

Cross recess countersunk head machine screws are designed to sit flush with the workpiece surface when installed into a pre-drilled countersunk hole. Both parts of the standard specify the same head profile with a 90° countersink angle, ensuring a smooth, snag-free surface. The cross recess centers the driving tool and facilitates both manual and automated assembly. Dimensions and technical requirements…

Slotted pan head machine screws are among the most fundamental and widely recognized fastener types in mechanical assembly. Defined by their distinctive flat-topped, round-sided head and a single straight slot for a flat-blade screwdriver, they offer a simple, tool-compatible solution for a broad range of fastening tasks. The dimensions and technical requirements for slotted pan head machine screws are defined…

Cross recessed pan head machine screws (also known as Phillips pan head machine screws) are one of the most widely used fastener types in mechanical and electronic equipment assembly. Characterized by a rounded, slightly domed head and a cross-shaped recess, they are designed for quick, efficient tightening using a standard Phillips screwdriver or power tool. The pan head design provides…

Grease nipples, also known as lubrication fittings or grease fittings, are small but essential components used to deliver lubricant (grease) into bearings, bushings, and other moving parts of machinery. They act as a one-way valve, allowing a grease gun to inject lubricant while preventing dirt and contaminants from entering. Available in various configurations—including straight, 45°, and 90° angled types—they provide…

Socket head cap screws, also known as Allen head screws or hex socket head cap screws, are precision fasteners characterized by a cylindrical head with a recessed hexagonal socket. This internal drive design allows for high torque application in confined spaces where traditional external drive screws cannot be used. Available in both metric (ISO 4762 / DIN 912) and inch (ASME B18.3) series, these screws are widely used in…
