Screwdriver Bits & Accessories Supplier | SINOLITE
From PH1 insert bits to 80 mm deep socket nut drivers, this category covers the accessories required to transfer torque from a drill or impact driver to different screws, nuts and hex fasteners. SINOLITE supplies S2 insert bits and power bits, magnetic and quick-change bit holders, magnetic nut setters, deep socket nut drivers and adjustable screw-depth accessories.
For screwdriver bits, check the fit between the bit tip and the actual fastener to reduce slipping and cam-out. For magnetic bit holders and nut setters, evaluate magnet retention, concentricity, locking performance and socket fit. Products intended for impact drivers should be confirmed as impact-rated rather than treated as interchangeable with standard bits.
Buyers can select products by drive profile, size, overall length, shank, material, surface finish, retention method, tool compatibility and packaging format.
Applications
● Construction, renovation and installation work
● Furniture, cabinet and woodworking assembly
● Roofing, HVAC and metal-building fastening
● Electrical and mechanical installation
● Automotive repair and equipment maintenance
● Repetitive screw-depth control
● Thin sheet metal cutting
Match the Bit, Holder and Fastener
SINOLITE offers Phillips, Pozidriv, Torx and Hex profiles in short insert-bit and longer power-bit configurations.
Insert bits are normally combined with a separate holder, making them suitable for bit sets and applications that require frequent profile changes. Longer power bits provide additional reach and can be selected for recessed fasteners, furniture assembly, installation work and other fastening tasks. PH, PZ, Torx and Hex profiles should not be treated as interchangeable, even when the sizes appear similar.
The bit holder determines how securely an insert bit is retained and how accurately torque is transferred. The current range includes:
● 75 mm and 125 mm magnetic bit holders with sleeves
● Quick-change magnetic bit holders
● Knurled holders for improved handling
● Stainless-steel and titanium-finished options
● Waist-shaped aluminium-head designs
● Hex-shank magnetic bit holders
Magnetic nut setters are intended for driving hex-head screws, nuts and self-drilling fasteners used in metal framing, roofing, HVAC installation, machinery assembly and maintenance work.
SINOLITE offers 48 mm and 65 mm magnetic nut setters. For recessed nuts or protruding threaded rods, the 80 mm deep socket nut driver provides a 32 mm socket depth and is available in 12, 13, 14, 15, 17 and 19 mm sizes.
Adjustable Screw Depth Control
The adjustable limiting clutch provides seven depth settings from 2.0 to 6.0 mm and connects through a 1/4-inch quick-change shank. It is used when screws must be installed to a controlled depth without damaging the workpiece surface.
This is particularly useful for repetitive installation in drywall, decking, panels, furniture and other applications where overdriven screws may damage the material or affect the finished appearance.
The sheet metal nibbler is different from the fastening products above. It converts compatible power-tool rotation into a cutting action for thin metal sheet.
Build a Complete Accessory Range for Your Market
Tool distributors and private-label brands can build a practical range by combining frequently used PH, PZ, Torx and Hex bits with different working lengths, magnetic holders, quick-change holders and nut setters.
For example, a distributor range may include:
● Short insert bits for multipiece sets
● Longer power bits for direct driving and extended reach
● 75 mm and 125 mm magnetic bit holders
● Quick-change holders for frequent bit replacement
● 48 mm and 65 mm magnetic nut setters
● 80 mm deep socket nut drivers for recessed fasteners
● Adjustable depth-control accessories
