Würth #8 x 1-5/8" Flat Head Assembly Screw Phillips Drive - Type 17 Auger Point Coarse Thread Black, 3670000074961 3500 - 3500/Box

#8 Flat Head Assembly Screw For Wood Projects

#8 x 1-5/8 flat head assembly screw is a case hardened screw with a coarse thread and black finish, so it handles demanding fastening jobs while keeping a consistent appearance on visible work. The Phillips drive head is designed for #2 Phillips drive bits, giving installers a familiar interface that works with standard drivers used in shops and on site. The flat head style lets the screw sit flush when properly driven into a countersunk hole, which helps panels draw tight without proud heads catching during use. The screw uses a Type 17 auger point, so it starts easily and cuts its way in, which helps reduce splitting when driving into wood or similar materials. The coarse threading pattern provides strong bite in softer substrates, helping joints pull together quickly during cabinet, fixture, or general assembly work.

Key Assembly Screw Details For Daily Work

• This #8 x 1-5/8 screw is case hardened, so it is manufactured for strength in fastening applications where repeated driver torque and holding power are important on the job.
• The coarse thread design lets the screw advance quickly through material, which helps parts clamp together firmly with fewer turns during production or installation.
• A Type 17 auger point cuts into the material as the screw starts, which promotes smoother driving and helps the point seat without heavy pre-driving force.
• The flat head style is made to sit level in a countersink, so surfaces remain smooth wherever a flush finish is required on cabinetry or built assemblies.
• The Phillips drive is sized for #2 Phillips drive bits, so installers can use standard bits already in regular drill and driver setups across the shop floor.
• A black finish gives the screw a dark appearance, which helps it blend visually in applications where exposed fastener heads need to match darker components.
• Lengths of 3/4 inch and 1 inch in this line are threaded fully, while all other sizes are threaded two thirds from the bottom of the screw, supporting consistent thread engagement patterns.
• The product is sold in full box quantities only, and discount is available for bulk box orders, which supports cost control when stocking for repeated fastening tasks.

Installation Use And Phillips Drive Fitment

This #8 x 1-5/8 flat head assembly screw uses a Phillips drive that is sized for #2 Phillips drive bits, so it pairs directly with standard bits commonly kept in installers drill and impact driver assortments. The coarse thread profile lets the screw draw into wood or similar materials quickly, so less driving time is needed as panels and components are pulled tight during assembly. A Type 17 auger point is designed to cut into the substrate as it starts, so the tip works its way in with reduced initial resistance. The flat head form is intended to seat in a countersunk hole so the head is flush, helping create even surfaces on cabinet faces, casework, or fixtures.

Assembly Screw Performance In Real Projects

Where This Wurth #8 Assembly Screw Fits

The Wurth #8 x 1-5/8 flat head assembly screw sits in the screws category under fasteners, so it is positioned for general fastening use in woodworking and related assembly work. The screw is case hardened, so it is built for applications where a strong, wear-resistant screw is preferred as drivers are applied repeatedly across large runs. Its coarse thread is tailored for materials where aggressive bite is useful, so it helps clamp components as the screw advances. The black finish supports use on projects with darker surfaces, so exposed heads align visually with dark hardware or panels. Within the product line, 3/4 inch and 1 inch lengths use full threading, while longer sizes are threaded two thirds from the bottom, so thread layout remains predictable from piece to piece in an assembly standard.

Details That Support Consistent Screw Results

This Type 17 auger point screw is designed to cut its way into the material, so it promotes a cleaner start that supports alignment when components are being drawn together. The flat head configuration is meant for countersunk holes, so when driven correctly the head rests level with the surface, helping joints close without snag points. The #2 Phillips drive sizing matches common driver bits, so crews can move from one fastening position to the next without changing to specialty tools. Case hardening provides a hardened outer structure, so the screw is suited to repeat driving in production-style assembly where consistent torque is applied. Coarse threads carry load through fewer turns, so installers can bring parts into final position efficiently across cabinets, furniture, or shop-built fixtures needing repeatable fastener behavior.

Buyer Questions About This Type 17 Screw
