For replacing loose handle fasteners, choose an M4 screw-and-sleeve set sized for your door; for back-to-back pull handles on a 1-3/4-inch door, choose a CRL through-bolt made for Variant pulls. The BlingKingdom set is suited to common handle repairs and 30–60 mm doors, while the 20-piece Auto-plaza set is better for keeping spare fasteners on hand. The CRL options are for a more specific pull-handle installation.

BlingKingdom M4 x 60 mm Door Handle Screws
This eight-set package is best for homeowners or maintenance workers replacing loose or damaged fasteners that connect door handles. The listed M4 x 60 mm screws are adjustable by cutting them to the required length, and the product is specified for doors 30–60 mm thick. The stainless-steel construction is described as rust-proof and durable.
Choose this if your door falls within the stated thickness range and you want multiple replacement sets. Limitation: it is not specified for doors outside the 30–60 mm range, so measure before ordering.
Four-Set M4 Door Handle Connecting Bolts
This four-set hardware option is best for a small repair when you need a limited number of connecting bolts and sleeves. Its listed screw size is M4 x 60 mm, the screw can be cut to fit, and the hardware is made from 304 stainless steel. Those details make it a straightforward option to compare with larger multipacks.
Choose this if you need a few replacement fasteners and want a cut-to-length screw. Limitation: the package contains four sets, which may not be enough for multiple doors or a larger maintenance supply.
Auto-plaza 20-Set M4 Connecting Screws
The 20-set Auto-plaza package is best for users repairing several handles or keeping replacement hardware available. The M4 x 60 mm screw-and-sleeve fasteners attach two handles together, and the listed screw can be cut to suit the fitting. Both the screw and sleeve have a Pozi head, according to the product details.
Choose this if quantity and cut-to-fit length matter more than buying only a few fasteners. Limitation: the supplied length may need adjustment; check the required fitting length before installation.
CRL TB4VPS Through-Bolts for Variant Pulls
This CRL hardware is best for mounting compatible Variant series pull handles back-to-back on a 1-3/4-inch wood or metal door. The listing says it can be used with any of the available styles for back-to-back mounting and identifies a satin-anodized finish. This is a more application-specific choice than general M4 handle screws.
Choose this if your pull handles are from the Variant series and the door is the specified thickness. Limitation: the stated application is limited to 1-3/4-inch doors and compatible Variant pulls.
CRL VTB4CH Through-Bolts for Variant Pull Handles
This CRL pair of through-bolts is best for a compatible Variant series adjustable pull handle installation on a 1-3/4-inch wood or metal door. The listed package includes a pair, and the hardware is specifically identified for Variant series pull handles. Its defined use helps distinguish it from general-purpose handle connecting screws.
Choose this if you need the listed pair for the stated Variant pull application. Limitation: the supplied information does not identify it as a universal fastener for other pull-handle designs.
Buying Guide: How to Choose Door Handle Through Bolts
What type of handle are you fastening?
Start by identifying whether you are repairing a lever or knob set that connects through the door, or mounting a pair of pull handles back-to-back. M4 screw-and-sleeve sets are listed for connecting handles together. The CRL products are identified for Variant series pull handles, so they are not interchangeable by assumption.
How thick is the door?
Measure the door before choosing hardware. BlingKingdom specifies a 30–60 mm door range. Both CRL options state a 1-3/4-inch door application. Do not rely on a screw’s nominal length alone to confirm fit; compare the door thickness and the handle’s fastening arrangement with the product details.
Do you need a cut-to-length screw?
Several M4 listings say the screw can be cut to fit. This can help when the supplied length is longer than the fitting requires, but measure carefully before cutting. The CRL listings describe specific pull-handle uses rather than stating that their bolts are cuttable.
How many sets should you buy?
A four-set package may suit a limited repair, while eight or 20 sets provide more fasteners for additional jobs or spares. Check whether the product’s included quantity matches the number of handle connections you need to secure.
Does the material or drive style matter?
The four-set M4 option lists 304 stainless steel, and BlingKingdom describes its fasteners as stainless steel. Auto-plaza lists Pozi heads on both screw and sleeve. Check the listed material and head style against the existing hardware and the tools available to you.
Frequently Asked Questions
What are door handle through bolts used for?
They pass through a door or handle assembly to secure connected hardware, such as two handles or back-to-back pull handles. Confirm the intended application for the specific fastener.
Are M4 x 60 mm bolts right for every door handle?
No. M4 x 60 mm describes the listed fastener size, but fit also depends on the door thickness and handle design. Check the product’s stated application and measure before buying.
Can door handle screws be shortened?
The BlingKingdom, four-set, and Auto-plaza listings state that their screws can be cut to the required length. The CRL product details provided do not make that claim.
Which option is intended for a 1-3/4-inch door?
Both CRL products are listed for mounting compatible Variant series pull handles on 1-3/4-inch wood or metal doors.
Should I replace a loose handle with a larger multipack?
Choose based on the number of fasteners needed. A smaller set may cover a limited repair, while a larger package provides more sets for additional repairs or spares.
