Würth #8 x 1-3/4" Flat Head Assembly Screw Phillips Drive - Sharp Point Coarse Thread Black, 3670000145961 4800 - 4800/Box

#8 Flat Head Assembly Screw For Woodwork

#8 x 1-5/8 flat head assembly screw gives a consistent fastener size for cabinet and woodworking assemblies where a standard #8 profile is already in use, helping keep drilling and bit selection straightforward across a job. The flat head design lets the screw seat flush in a countersunk hole, which keeps surfaces smooth on face frames, brackets, or hardware mounting points. The Phillips drive works with common #2 Phillips drive bits, so installers and shop crews can run these screws using standard drivers without changing tools. The screw uses a sharp point with coarse thread, which is suited to driving into material where quick biting and pull-down are needed. This version has a black finish, supporting projects where the fastener needs to visually blend with darker components or trim. Case hardened construction provides a fastener engineered for assembly use in woodworking environments.

Key Fastener Details That Support Your Work

• The #8 screw size ties directly to a common woodworking fastener standard, so it integrates into existing drilling patterns and hardware layouts on cabinets and fixtures.
• The 1-5/8 inch length provides a longer bite than shorter variants in this product line, suiting assemblies where more thread engagement into the substrate is needed for pull resistance.
• The flat head profile is designed to sit flush in a countersunk recess, which keeps surfaces clean where hardware, brackets, or trim pieces must sit tight against the material.
• The Phillips drive works with #2 Phillips drive bits, aligning with drivers already used in most shops and on install sites for straightforward fastening.
• The sharp point with coarse thread style is tailored to cut quickly into the material and draw components together efficiently during cabinet or wood assembly tasks.
• The black finish offers a dark fastener appearance that works in applications where visible screws should coordinate with darker fittings, hinges, or trim elements.
• The screw is case hardened, giving a fastener structure developed for assembly use where repeated driving in woodworking environments is part of daily work.
• The line offers 3/4 inch and 1 inch fully threaded versions, while longer sizes such as this follow the rule of being threaded two-thirds from the bottom of the screw for targeted grip.

Assembly Screw Details For Practical Installation

This screw is part of a line where 3/4 inch and 1 inch lengths are threaded fully, while all other sizes are threaded two-thirds from the bottom of the screw. For the 1-5/8 inch size, that two-thirds threading from the tip focuses the grip in the material being fastened, which supports drawing one piece tight to another in typical cabinet or fixture assembly. The flat head is intended for countersunk holes, so once seated the head aligns with or slightly below the surface, helping other hardware or trim sit correctly. With a Phillips drive that uses #2 Phillips drive bits, installation fits directly into workflows that rely on standard bit assortments. The case hardened description refers to how the fastener has been treated, tying it to assembly-driven applications in woodworking environments.

Using This Wurth Screw In Woodworking Projects

Where This #8 Black Screw Fits Best

This Wurth #8 x 1-5/8 inch flat head assembly screw sits within the Fasteners|Screws category and the Screws product class, identifying it for fastening roles in woodworking and cabinet-related assemblies. The coarse thread and sharp point work together to start quickly in wood-based materials, which is important when parts need to be pulled together without pre-tapping. Because only the lower two-thirds of this longer screw is threaded, it focuses the pulling action into the base piece, which is valuable when attaching face frames, stretchers, or structural strips where one component should move tightly against another. The black finish supports situations where screw heads remain visible on darker interior panels or trim, reducing contrast around hinge plates, brackets, or other mounted hardware in those areas.

Details That Help Repeatable Results On Site

The reliance on a #2 Phillips drive bit means this screw runs with a driver size that installers and shop teams already carry, which streamlines repetitive driving during production builds or on-site cabinet installs. The flat head geometry, designed for countersunk holes, contributes to repeatable seating depth: once the proper countersink is established, each screw pulls down to a consistent flush position, helping doors, slides, or brackets sit even. Case hardened construction supports the screw as a dedicated assembly fastener in woodworking environments, where multiple screws must be driven in sequence during carcass building or fixture mounting. Because 3/4 inch and 1 inch versions in this line are fully threaded while longer sizes, including this one, are threaded two-thirds from the bottom, installers can match threading style to how tightly they want components drawn together through the unthreaded shank area. This pattern-based approach to length and threading helps standardize outcomes across repeated cabinet or fixture layouts. The presence of both the manufacturer part number 3670000145961 4800 and the Wurth branding allows shops to specify the same screw reliably for future production runs, supporting consistent fastener performance across multiple projects delivered to customers.
