You’ll see a few names for this style. Common terms include:

• 5-point star or security star
• Pentalobe (five-lobe profile)
• Torx Plus Security (often labeled IPR sizes)
• Security Torx (5-point) with codes like TS or TT

Naming can vary by manufacturer and listing. On Walmart.com, you may see size codes such as TS10–TS50, TT15–TT45, or IPR8–IPR60 alongside "5 point." Most bits use a 1/4 inch hex shank, with common lengths around 1–2 inches, and some are magnetic. Checking the product title and photos for “5 point” and the specific size can help you select the right fit.

It’s often called a 5-point star screw, pentalobe screw, or security star screw. These fasteners are designed for tamper resistance and use a matching 5-point driver bit.

• Match the bit system: Look for TS, TT, or IPR size codes in the bit set you choose.
• Check for a center pin: If present, you’ll need a tamper-proof bit with a hole.
• Count the lobes: Five lobes require a 5-point bit; a 6-lobe Torx won’t fit properly.

Using the correct driver helps reduce the chance of stripping. If you’re unsure, multi-bit security sets on Walmart.com can offer a range of compatible sizes.

Traditional Torx is a 6-point star. However, 5-point variants also exist and are used for security applications. Listings may label 5-point tools as 5 point, security star, pentalobe, or Torx Plus Security (often with IPR sizes).

• Size markings vary: Many 6-point bits use T sizes, while 5-point may show TS, TT, or IPR. Some listings use T with 5-point—so always confirm the “5 point” callout.
• Don’t mix profiles: A 6-point Torx bit typically won’t work on a 5-point screw and could cause damage.

Checking product photos and titles for the number of lobes can help you pick the correct profile.

For best results, use a matching 5-point bit. Improvised tools (like flat-blade drivers or pliers) can slip, damage the screw head, or cause injury. If you don’t have the exact bit, consider:

• Security bit sets that include 5-point sizes (look for TS10–TS50 or IPR ranges).
• 1/4 inch hex shank bits to fit common hand drivers and drills.
• Order pickup or delivery options on Walmart.com for quicker access.

To identify the right size, count the lobes (five), check for a center pin, and compare the screw to the size range listed in the set. Choosing the correct profile can help prevent stripping.

Start by confirming it’s a 5-lobe screw, then size up:

• Check markings: Some fasteners or packaging list a size (e.g., TS25 or IPR20).
• Compare physically: Hold the bit to the screw; the lobes should seat snugly without play.
• Use a range: Sets covering TS10–TS50 or IPR sizes provide flexibility when markings aren’t available.
• Match the shank and length: Most bits here use a 1/4 inch hex shank; choose 1" for tight spaces or 2" for extra reach. Magnetic tips can help hold fasteners.

Taking a clear photo or the fastener itself to compare with product images and size charts can make selection easier.
