Discover more about the Imperial Torx Pan Head Screws range.

Accu’s Imperial Torx Pan Head Screws are a type of machine screw fitted with a Torx Drive, also commonly referred to as a Star Drive. Torx Screws like this are designed for higher torque applications and provide increased resistance to cam-out over traditional drives such as Flat Head or Phillips Head screws.

As its name suggests, the Pan Head of this type of Torx Screw is similar in shape to an upside down frying pan. The top of the head is either flat or slightly rounded, with straight sides free from sharp or pointed edges.

Imperial Torx Pan Head Screws are compatible with our range of Torx Drive Bits, in Torx size T5 up to T50. Alternatively, a Torx Screwdriver, also commonly known as a Star Screwdriver, can also be used to install and remove this type of Pan Head Screw.

Materials

Imperial Torx Pan Screws are manufactured in A2 Stainless Steel as standard with a wide array of materials avalible to suit your project needs.

Fortify your Imperial Torx Pan Head Screws with Accu’s advanced thread-locking patches. Whether it’s AccuLock Threadlocker for standard security, Anu-Lok 180 for extra resilience, or Precote 80 for elite performance, your fasteners stay locked. Opt for AccuBlack chemical blackening for a stealthy, low-glare aesthetic with a premium edge.

Imperial Sizes

Accu’s Imperial Torx Pan Head Screws are available in thread sizes ranging from from No. 4 up to ⅜” and thread lengths of ¼” to 1.½”.

Metric Sizes

Accu also lists Metric Torx Pan Head Screws in Bumax 88, A2 and A4 Stainless Steel, in thread sizes M1.6 to M10.
