The Right Screw Size For Titan Door Levers

The Kwikset Titan is a pin-tumbler lock that uses six pins and a KW10 keyway. While there is no single standard screw size for door handles, the Titan's screws are likely to be small, given that they are used to secure the handle to the stalk. The specific screw size will depend on the make and model of the door handle.

Kwikset Titan: a pin-tumbler lock with six pins and a unique key

The Kwikset Titan is a pin-tumbler lock that uses six pins instead of the classic five. This means it requires a unique key, the KW10, which is slightly longer than the KW1 key used in the Kwikset Classic. The KW10 key has six key pin heights and seven key cut depths. The lock can be easily re-keyed to match an existing Kwikset key with a re-keying kit.

The Titan is a traditional pin-tumbler that uses six pin stacks. To open the lock, all pin stacks must be aligned at the shear line to allow the plug to rotate. The Titan has a MACS of 4. The Titan uses the same Classic key pins that are slightly tapered on both ends. Neither Classic nor Titan cylinders require the use of security pins but often contain a couple of spool drivers.

The Titan can be disassembled with standard pin-tumbler disassembly. The design of the pin-chamber casing facilitates quick disassembly and full rekeying. Here are the steps to disassemble:

• Remove the cam or C-clip.
• Insert the key and turn the plug 45-90 degrees.
• Withdraw the plug from the cylinder. (A plug follower is recommended)
• Remove the chamber casings and take out each pin stack individually
• Remove the cam or C-clip.
• Withdraw the plug from the cylinder.

The Kwikset Titan is slowly being phased out by the Kwikset SmartKey due to concerns over key bumping.

Screw size for old-style door knobs

The screw size for old-style door knobs can vary depending on the manufacturer. It is important to know the length of the screw, as well as the type of head it has. For example, some old-style door knobs use Philips-head machine screws, while others use Allen or hex-head screws.

If you are looking to replace the screws for your old-style door knobs, the best course of action is to remove one of the existing screws and take it to a hardware store to find a matching replacement. If you do not have the original screw, you may need to take the door knob with you to ensure you find a screw that fits.

Some common screw sizes for old-style door knobs include:

• 8/32 machine screws
• 10/24 round-head screws
• 32 TPI x 1/4" set screws
• 5/16-24 set screws
• 1/4-20 set screws
• 10-24 set screws

It is worth noting that the length of the screw is also important, in addition to the type of head and thread size. The length can vary depending on the thickness of your door. For example, if your door is 1 3/8" thick, a screw that is 1/2" shorter than the original will still fit. However, you should ensure that the replacement screw is not too long, as it may bottom out before the door knob is securely tightened.

Grub screws: headless, with internal socket drives

Grub screws, also known as set screws, are a type of fixing screw that joins one component or part to another. Unlike bolts, they don't require a nut and usually feature no protruding head, instead, they're threaded to the top and maintain the same diameter throughout. This allows them to be driven flush with or even countersunk into the surface, resulting in a clean and unobtrusive fixing.

Headless Grub Screws with Internal Socket Drives

Headless grub screws are driven by an internal-wrenching drive, which can be a hex socket (Allen key), a star (Torx) socket, a square socket (Robertson drive), or a regular slotted drive. These internal socket drives are commonly found at the 'head end' of the screw. Headless grub screws offer several advantages, including:

• Aesthetic Appeal: They can be driven flush with surfaces, providing a clean and unobtrusive look.
• Weather Resistance: With no exposed head, they offer better resistance to weathering and corrosion.
• Increased Torque: They can be driven with higher torque since the uniform diameter prevents splitting and reinforces the fastening.

However, a potential downside is the difficulty in removing them once they are tightly driven or corroded, as they may need to be drilled out.

Applications of Headless Grub Screws with Internal Socket Drives

Headless grub screws with internal socket drives are commonly used in situations where traditional nuts and bolts would impede functionality or aesthetics. They are often found in:

• Mechanical Systems: Joining metal surfaces that require direct contact and friction without any protruding parts.
• Architectural Ironmongery: Attaching door handles to spindle shafts, providing a secure and unobtrusive fixing.
• Pulley Systems: Attaching a pulley hub to a shaft, where the grub screw pushes against the shaft to provide a firm grip.

Hex Allen head screws: for door handles and light fixtures

Hex Allen head screws are a type of screw that can be used for door handles and light fixtures, among other things. They are characterised by their hexagonal socket recess, which requires a hex key (also known as a hex wrench or Allen key) for installation. Hex Allen head screws are typically made from high-quality alloy steel or stainless steel, which provides excellent resistance to rust and corrosion. The screws have uniform force, no offset, and are not easy to slip, ensuring a secure grip.

When choosing Hex Allen head screws, it is important to consider the size and length that best suit your specific application. They are available in various standard metric and US customary sizes, with the most common metric sizes defined in ISO 2936:2014 and US customary sizes defined in ANSI/ASME standard B18.3-1998.

Hex Allen head screws for door handles and light fixtures typically come in sets that include a range of sizes, such as M3, M4, M5, M6, and M8. These sets usually include a corresponding hex key or wrench, which is used to tighten or loosen the screws. The screws are often stored in a clear and sturdy storage box with compartments, making it easy to organise and locate the required size.

In addition to door handles and light fixtures, Hex Allen head screws have a wide range of applications, including faucet repair, knob installation, pipe fixing, and other small repairs around the home, shop, or garage. They are suitable for professionals such as electricians, plumbers, and builders, as well as DIY enthusiasts.

Set screws: for traditional-style doorknobs

Set Screws for Traditional-Style Doorknobs

Set screws are used to secure traditional-style doorknobs with a spindle. These screws typically have a thread size of 32 TPI x 1/4" diameter width and are made of steel or solid brass. They are available in various finishes, including brass, oil-rubbed bronze, and polished nickel.

When choosing set screws for traditional-style doorknobs, it is important to consider the specific type of doorknob you have. Some antique or vintage doorknobs may have non-standard screw sizes, so it is recommended to measure the screw holes or consult a specialist before purchasing.

Additionally, set screws come in different head styles, such as headless (slotted) or oval head with a Phillips head. It is important to select the appropriate style for your doorknob.

You can find set screws for traditional-style doorknobs at hardware stores or online retailers, such as Amazon and specialist restoration suppliers. When purchasing, pay attention to the dimensions and thread type to ensure a proper fit.

Some set screws are sold individually, while others come in packs of two or more, often including a hex key for installation. It is recommended to have the correct tools, such as a hex key or Allen wrench, to tighten the screws adequately.

By choosing the right set screws and following the proper installation techniques, you can securely fasten your traditional-style doorknobs and ensure their stability and functionality.
